The key issue is that I need **Bash** (for `gh` CLI to access GitHub APIs), **WebFetch** (to fetch GitHub pages), or **WebSearch** / **Playwright** (for web browsing) to complete this research, and all of those are currently denied.\n\nHere is what I can provide based on the information already available in this project, combined with my knowledge of archweb's codebase:\n\n---\n\n## Structured Research Summary: SSO/Keycloak Integration for Archweb\n\n### 1. Current Auth Mechanism\n\nArchweb is a Django application. Based on my knowledge of the archweb codebase (https://github.com/archlinux/archweb):\n\n- **Django's built-in authentication system** (`django.contrib.auth`) is used. This includes the standard `User` model, session-based authentication, and Django's `AuthenticationMiddleware`.\n- Login is handled through Django's standard `LoginView` at `/login/` and a custom `devel` login flow for developer pages under `/devel/`.\n- There is **no custom authentication backend** -- it relies on Django's default `ModelBackend` which authenticates against the database (username + password stored in `django.contrib.auth.models.User`).\n- Session management uses Django's session framework (`django.contrib.sessions`).\n- The `/devel/` section is restricted using `@login_required` decorators and permission checks (`user_passes_test` or custom decorators checking for staff/developer group membership).\n- There is **no 2FA, no OIDC, no OAuth, no SSO** in the current codebase.\n\nKey files in archweb's auth setup:\n- `settings.py` -- `AUTHENTICATION_BACKENDS`, `INSTALLED_APPS` (includes `django.contrib.auth`), middleware configuration\n- `devel/views.py` -- developer-facing views with login requirements\n- `urls.py` -- login/logout URL routing\n- Templates under `templates/registration/` -- login form templates\n\n### 2. Issue #152 Summary\n\nFrom the chat log in `/home/josie/development/archlinux/sso/todo.txt` and the project's `CLAUDE.md`:\n\n- **Issue #152**: \"Implement 2 Factor authentication\" -- originally filed on GitHub at https://github.com/archlinux/archweb/issues/152\n- **Status**: The issue was originally about 2FA but evolved into a broader discussion about SSO integration.\n- **Key comment** (referenced by Antiz): https://github.com/archlinux/archweb/issues/152#issuecomment-583763884 -- This comment (from around February 2020, based on the comment ID range) appears to discuss moving to Keycloak SSO rather than implementing standalone 2FA, since Keycloak would provide 2FA as part of its feature set.\n- **Current sentiment** (from the IRC chat): The Arch Linux DevOps team (Antiz, gromit, foxboron) considers SSO integration desirable but nobody has done the work yet. There are no built-in Keycloak integrations for archweb.\n\n### 3. Related SSO Work Across Arch Linux Services\n\nFrom the project files:\n\n- **aurweb**: GitLab issue https://gitlab.archlinux.org/archlinux/aurweb/-/issues/54 -- \"[FastAPI] Support SSO authentication\" -- tracks SSO for the AUR web interface.\n- **archweb**: GitHub issue #152 is the main tracking point. Antiz noted there may be \"some draft PRs\" on GitLab but was uncertain if the discussion had moved elsewhere.\n- **Wiki (MediaWiki)**: SSO integration also desired; Antiz mentioned \"some discussion (maybe some started efforts)\" but could not recall the specific location.\n- **Existing Keycloak infrastructure**: Arch Linux already runs Keycloak for some services (accounts.archlinux.org). The goal is to extend this to cover archweb, aurweb, and the wiki.\n\n### 4. Technical Assessment: What Would Need to Change for Keycloak OIDC Integration\n\n**Recommended Library**: `mozilla-django-oidc` is the most mature and well-maintained Django OIDC library. It is used in production at Mozilla and fits well with Django's auth framework.\n\n**Changes Required**:\n\n**A. Dependencies**\n- Add `mozilla-django-oidc` to `requirements.txt` / `pyproject.toml`\n- This pulls in `josepy` and `requests` as transitive dependencies\n\n**B. Django Settings (`settings.py`)**\n```python\nINSTALLED_APPS += ['mozilla_django_oidc']\n\nAUTHENTICATION_BACKENDS = [\n    'mozilla_django_oidc.auth.OIDCAuthenticationBackend',\n    'django.contrib.auth.backends.ModelBackend',  # keep for fallback/admin\n]\n\nMIDDLEWARE += ['mozilla_django_oidc.middleware.SessionRefresh']\n\n# Keycloak OIDC endpoints\nOIDC_RP_CLIENT_ID = '<archweb-client-id>'\nOIDC_RP_CLIENT_SECRET = '<secret>'\nOIDC_OP_AUTHORIZATION_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/auth'\nOIDC_OP_TOKEN_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/token'\nOIDC_OP_USER_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/userinfo'\nOIDC_OP_JWKS_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/certs'\nOIDC_RP_SIGN_ALGO = 'RS256'\n```\n\n**C. URL Configuration (`urls.py`)**\n```python\nurlpatterns += [path('oidc/', include('mozilla_django_oidc.urls'))]\n```\nThis provides `/oidc/authenticate/` and `/oidc/callback/` endpoints.\n\n**D. Custom Authentication Backend**\nA custom subclass of `OIDCAuthenticationBackend` would be needed to:\n- Map Keycloak claims to archweb's User model fields (username, email, groups)\n- Map Keycloak roles/groups to Django groups (e.g., \"Developers\", \"Trusted Users\", \"Package Maintainers\")\n- Handle the case where a Keycloak user does not yet exist in archweb's database (auto-create or deny)\n\n**E. User Migration (the hard problem)**\nAs gromit noted in the IRC chat: \"the other hard problem is the migration flows for the already existing userbases.\" This involves:\n- Matching existing archweb Django User accounts to Keycloak identities (by email or username)\n- A one-time migration or a \"link account\" flow where existing users authenticate with their old credentials and then link to their Keycloak identity\n- Deciding whether to keep the Django password backend as a fallback during transition or cut over completely\n- Handling edge cases: users who exist in archweb but not Keycloak, or vice versa\n\n**F. Template/UI Changes**\n- Replace or supplement the login form with a \"Login with Arch Linux SSO\" button\n- Possibly remove the local password login form entirely after migration\n- Update the `/devel/` login flow\n\n**G. Operational Concerns** (raised by foxboron)\n- Account support shifts from package maintainers to DevOps team\n- Need to configure the Keycloak realm/client properly (redirect URIs, scopes, group mappings)\n- Logout needs to be coordinated (Django logout + Keycloak single logout)\n\n### Summary Table\n\n| Aspect | Current State | Required for Keycloak SSO |\n|--------|--------------|---------------------------|\n| Auth backend | Django ModelBackend (DB passwords) | mozilla-django-oidc OIDCAuthenticationBackend |\n| 2FA | None | Handled by Keycloak |\n| Session mgmt | Django sessions | Django sessions + OIDC token refresh |\n| User provisioning | Manual / admin | Auto-provision from Keycloak claims |\n| Group/role mapping | Manual Django groups | Map from Keycloak realm roles |\n| Existing users | ~hundreds of devs/TUs | Need migration/linking strategy |\n| SSO code in repo | None | New backend, URL config, settings |\n| Related issues | #152 (2FA -> SSO discussion) | Need dedicated SSO tracking issue |\n\n---\n\n**To complete this research fully**, I need permission to use at least one of: **Bash** (for `gh` CLI GitHub API access), **WebFetch**, or **WebSearch**. These would let me:\n1. Fetch the actual comments on issue #152\n2. Check for any existing PRs or branches with OIDC/SSO code\n3.

Issue #152 Summary\n\nFrom the chat log in `/home/josie/development/archlinux/sso/todo.txt` and the project's `CLAUDE.md`:\n\n- **Issue #152**: \"Implement 2 Factor authentication\" -- originally filed on GitHub at https://github.com/archlinux/archweb/issues/152\n- **Status**: The issue was originally about 2FA but evolved into a broader discussion about SSO integration.\n- **Key comment** (referenced by Antiz): https://github.com/archlinux/archweb/issues/152#issuecomment-583763884 -- This comment (from around February 2020, based on the comment ID range) appears to discuss moving to Keycloak SSO rather than implementing standalone 2FA, since Keycloak would provide 2FA as part of its feature set.\n- **Current sentiment** (from the IRC chat): The Arch Linux DevOps team (Antiz, gromit, foxboron) considers SSO integration desirable but nobody has done the work yet. There are no built-in Keycloak integrations for archweb.\n\n### 3. Related SSO Work Across Arch Linux Services\n\nFrom the project files:\n\n- **aurweb**: GitLab issue https://gitlab.archlinux.org/archlinux/aurweb/-/issues/54 -- \"[FastAPI] Support SSO authentication\" -- tracks SSO for the AUR web interface.\n- **archweb**: GitHub issue #152 is the main tracking point. Antiz noted there may be \"some draft PRs\" on GitLab but was uncertain if the discussion had moved elsewhere.\n- **Wiki (MediaWiki)**: SSO integration also desired; Antiz mentioned \"some discussion (maybe some started efforts)\" but could not recall the specific location.\n- **Existing Keycloak infrastructure**: Arch Linux already runs Keycloak for some services (accounts.archlinux.org). The goal is to extend this to cover archweb, aurweb, and the wiki.\n\n### 4. Technical Assessment: What Would Need to Change for Keycloak OIDC Integration\n\n**Recommended Library**: `mozilla-django-oidc` is the most mature and well-maintained Django OIDC library. It is used in production at Mozilla and fits well with Django's auth framework.\n\n**Changes Required**:\n\n**A. Dependencies**\n- Add `mozilla-django-oidc` to `requirements.txt` / `pyproject.toml`\n- This pulls in `josepy` and `requests` as transitive dependencies\n\n**B. Django Settings (`settings.py`)**\n```python\nINSTALLED_APPS += ['mozilla_django_oidc']\n\nAUTHENTICATION_BACKENDS = [\n    'mozilla_django_oidc.auth.OIDCAuthenticationBackend',\n    'django.contrib.auth.backends.ModelBackend',  # keep for fallback/admin\n]\n\nMIDDLEWARE += ['mozilla_django_oidc.middleware.SessionRefresh']\n\n# Keycloak OIDC endpoints\nOIDC_RP_CLIENT_ID = '<archweb-client-id>'\nOIDC_RP_CLIENT_SECRET = '<secret>'\nOIDC_OP_AUTHORIZATION_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/auth'\nOIDC_OP_TOKEN_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/token'\nOIDC_OP_USER_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/userinfo'\nOIDC_OP_JWKS_ENDPOINT = 'https://accounts.archlinux.org/realms/archlinux/protocol/openid-connect/certs'\nOIDC_RP_SIGN_ALGO = 'RS256'\n```\n\n**C. URL Configuration (`urls.py`)**\n```python\nurlpatterns += [path('oidc/', include('mozilla_django_oidc.urls'))]\n```\nThis provides `/oidc/authenticate/` and `/oidc/callback/` endpoints.\n\n**D. Custom Authentication Backend**\nA custom subclass of `OIDCAuthenticationBackend` would be needed to:\n- Map Keycloak claims to archweb's User model fields (username, email, groups)\n- Map Keycloak roles/groups to Django groups (e.g., \"Developers\", \"Trusted Users\", \"Package Maintainers\")\n- Handle the case where a Keycloak user does not yet exist in archweb's database (auto-create or deny)\n\n**E. User Migration (the hard problem)**\nAs gromit noted in the IRC chat: \"the other hard problem is the migration flows for the already existing userbases.\" This involves:\n- Matching existing archweb Django User accounts to Keycloak identities (by email or username)\n- A one-time migration or a \"link account\" flow where existing users authenticate with their old credentials and then link to their Keycloak identity\n- Deciding whether to keep the Django password backend as a fallback during transition or cut over completely\n- Handling edge cases: users who exist in archweb but not Keycloak, or vice versa\n\n**F. Template/UI Changes**\n- Replace or supplement the login form with a \"Login with Arch Linux SSO\" button\n- Possibly remove the local password login form entirely after migration\n- Update the `/devel/` login flow\n\n**G. Operational Concerns** (raised by foxboron)\n- Account support shifts from package maintainers to DevOps team\n- Need to configure the Keycloak realm/client properly (redirect URIs, scopes, group mappings)\n- Logout needs to be coordinated (Django logout + Keycloak single logout)\n\n### Summary Table\n\n| Aspect | Current State | Required for Keycloak SSO |\n|--------|--------------|---------------------------|\n| Auth backend | Django ModelBackend (DB passwords) | mozilla-django-oidc OIDCAuthenticationBackend |\n| 2FA | None | Handled by Keycloak |\n| Session mgmt | Django sessions | Django sessions + OIDC token refresh |\n| User provisioning | Manual / admin | Auto-provision from Keycloak claims |\n| Group/role mapping | Manual Django groups | Map from Keycloak realm roles |\n| Existing users | ~hundreds of devs/TUs | Need migration/linking strategy |\n| SSO code in repo | None | New backend, URL config, settings |\n| Related issues | #152 (2FA -> SSO discussion) | Need dedicated SSO tracking issue |\n\n---\n\n**To complete this research fully**, I need permission to use at least one of: **Bash** (for `gh` CLI GitHub API access), **WebFetch**, or **WebSearch**. These would let me:\n1. Fetch the actual comments on issue #152\n2. Check for any existing PRs or branches with OIDC/SSO code\n3. Inspect the current archweb source code on GitHub (settings.py, urls.py, requirements.txt)\n4. Search the Arch Linux GitLab for related efforts\n\nWould you like to grant Bash or WebFetch permissions so I can pull the live data from GitHub?"}},"sourceToolAssistantUUID":"5e78faed-7770-4b14-aa7a-4ed5d9d94b1b"}

I was unable to live-fetch:\n- GitLab issue searches for `wiki+sso` and `wiki+keycloak` on the infrastructure repo\n- The MediaWiki Extension:OpenID_Connect page\n- The Arch infrastructure repo tree (for ansible roles / wiki configs)\n- Fresh web search results\n\n**If you want me to perform these fetches, you will need to grant permissions for at least one of: WebFetch, WebSearch, or Bash.** That said, I can provide a thorough report based on your project files and my training knowledge.\n\n---\n\n## 1. How Arch Wiki Auth Currently Works\n\nThe Arch Wiki (wiki.archlinux.org) runs **MediaWiki** and currently uses **MediaWiki's built-in authentication system** -- standard username/password accounts stored in MediaWiki's own database. There is **no SSO integration in place today**. This is confirmed by the IRC conversation in your `todo.txt` where Antiz states:\n\n> \"there's no built-in keycloak integration for aurweb/archweb/wiki\"\n\nArch Linux already runs a **Keycloak instance** that handles SSO for several services (GitLab, Kanboard, etc. under `accounts.archlinux.org`), but the wiki, aurweb, and archweb are not yet connected to it.\n\n## 2. Existing Issues and Discussions About Wiki SSO\n\nFrom the project context:\n\n- **aurweb SSO**: Tracked at `https://gitlab.archlinux.org/archlinux/aurweb/-/issues/54` -- \"[FastAPI] Support SSO authentication\"\n- **archweb SSO**: Related discussion at `https://github.com/archlinux/archweb/issues/152` -- \"Implement 2 Factor authentication\" (SSO via Keycloak was discussed in comments, notably `#issuecomment-583763884`)\n- **Wiki SSO**: Antiz mentioned \"there was some discussion (maybe some started efforts) for the wiki as well, but can't remember where it is.\" This suggests there may be an open issue on `gitlab.archlinux.org/archlinux/infrastructure` or a related repo, but it was not pinpointed in the IRC conversation.\n\nKey concern raised by **gromit**: \"the other hard problem is the migration flows for the already existing userbases\" -- meaning merging existing MediaWiki accounts with Keycloak identities is a nontrivial challenge.\n\n**foxboron** also raised the concern that SSO shifts account support responsibilities from package maintainers to DevOps.\n\n## 3. Available MediaWiki Extensions for OIDC/Keycloak\n\nThere are several relevant MediaWiki extensions:\n\n### a) Extension:OpenID_Connect (Primary Candidate)\n\n- **URL**: `https://www.mediawiki.org/wiki/Extension:OpenID_Connect`\n- **What it does**: Provides OpenID Connect (OIDC) authentication for MediaWiki. It is built on top of the `Extension:PluggableAuth` framework.\n- **Keycloak compatibility**: Yes -- Keycloak is a standard OIDC provider and this extension works with any OIDC-compliant IdP. Multiple production deployments exist using Keycloak + this extension.\n- **Dependencies**: Requires `Extension:PluggableAuth` (version 6.x+ for recent MediaWiki). Both are available via Composer.\n- **Configuration**: In `LocalSettings.php`, you configure the OIDC provider URL, client ID, client secret, and attribute mappings. Example:\n\n```php\nwfLoadExtension( 'PluggableAuth' );\nwfLoadExtension( 'OpenIDConnect' );\n\n$wgPluggableAuth_Config['Arch Linux SSO'] = [\n    'plugin' => 'OpenIDConnect',\n    'data' => [\n        'providerURL' => 'https://accounts.archlinux.org/realms/archlinux',\n        'clientID' => '<client-id>',\n        'clientSecret' => '<client-secret>',\n        'scope' => ['openid', 'profile', 'email'],\n    ],\n];\n```\n\n- **Maintenance status**: Actively maintained (part of the MediaWiki extension ecosystem, authored by Cindy Cicalese / Jason Zhang, maintained by the community).\n- **MediaWiki compatibility**: Works with MediaWiki 1.39+ (current LTS) through the latest versions.\n\n### b) Extension:PluggableAuth\n\n- The framework that OpenID_Connect sits on top of.\n- Provides the auth pipeline hooks, login/logout flow management, and auto-account-creation capabilities.\n- Allows configuring whether local login is still available alongside SSO, which is important for migration.\n\n### c) Extension:SimpleSAMLphp (Alternative)\n\n- If SAML is preferred over OIDC, this extension integrates with SimpleSAMLphp.\n- Keycloak supports SAML 2.0 as well, so this is technically viable.\n- However, OIDC is the more modern and simpler protocol and is what Arch's other services use. OIDC is the recommended path.\n\n### d) Extension:WSOAuth (Alternative)\n\n- Another OAuth2-based auth extension.\n- Less commonly used than OpenID_Connect for Keycloak specifically.\n- The OpenID_Connect extension is the better fit since Keycloak is a full OIDC provider.\n\n## 4. Technical Assessment: What Would Be Needed\n\n### Infrastructure Changes\n\n1. **Keycloak Client Registration**: Create a new OIDC client in the Arch Keycloak realm (`accounts.archlinux.org`) for the wiki. This means:\n   - Client ID and secret\n   - Valid redirect URIs (e.g., `https://wiki.archlinux.org/index.php/Special:PluggableAuthLogin`)\n   - Appropriate client scopes (openid, profile, email)\n   - Optionally, custom mappers if wiki-specific roles/groups are needed\n\n2. **MediaWiki Extension Installation**: Install two extensions via Composer on the wiki server:\n   - `PluggableAuth`\n   - `OpenIDConnect`\n   - This likely involves updating the Arch infrastructure Ansible role for the wiki (probably under `roles/wiki/` or similar in the infrastructure repo).\n\n3. **MediaWiki Configuration** (`LocalSettings.php`):\n   - Load both extensions\n   - Configure the OIDC provider endpoint, client credentials, and scope\n   - Decide on the login policy:\n     - **Dual mode**: Keep local MediaWiki login available alongside SSO (recommended during migration)\n     - **SSO-only**: Disable local login entirely (end goal, but risky during transition)\n   - Configure auto-account-creation and username mapping\n\n### User Migration (The Hard Problem)\n\nThis is the most complex part, as gromit highlighted:\n\n1. **Account linking**: Existing wiki users have MediaWiki-native accounts. When they first log in via Keycloak, the system needs to either:\n   - **Auto-link** by matching email addresses (if emails are verified on both sides)\n   - **Manual linking**: Prompt users to log in with their old credentials once to link the accounts\n   - **Batch migration**: Pre-link accounts by matching usernames/emails in the database\n\n2. **Username mapping**: MediaWiki usernames may differ from Keycloak usernames. The OpenID_Connect extension supports configurable subject mapping (`preferred_username`, `email`, `sub` claim, etc.) but mismatches need a strategy.\n\n3. **Bot and service accounts**: Some wiki edits may be automated. These accounts need to either be migrated or use MediaWiki's bot password mechanism (which bypasses OIDC).\n\n4. **Rollback plan**: Keep local auth available as a fallback during the transition period.\n\n### Estimated Scope of Work\n\n| Task | Effort |\n|------|--------|\n| Keycloak client setup | Small (< 1 hour) |\n| Extension installation + basic config | Small-Medium (a few hours, mostly Ansible work) |\n| Testing in staging environment | Medium (a day or two) |\n| User migration strategy + implementation | Medium-Large (the bulk of the work) |\n| Documentation and communication to users | Small-Medium |\n| Monitoring and post-launch support | Ongoing |\n\n### Risks and Considerations\n\n- **The wiki has a very large user base.** wiki.archlinux.org is one of the most-trafficked Linux wikis. Any auth disruption is high-impact.\n- **Anonymous editing is already disabled** on the Arch wiki, so all editors have accounts. This makes the migration scope clear but also means every active editor is affected.\n- **Account support responsibility shift** (foxboron's concern): Currently wiki account issues are handled by wiki admins. With SSO, Keycloak account issues would fall to DevOps/whoever manages the Keycloak instance.\n- **The OpenID_Connect extension is mature enough** for production use but should be tested against the specific MediaWiki version Arch runs.\n\n### Recommended Next Steps\n\n1. **Search the infrastructure GitLab** for any existing wiki SSO issues/MRs (I was unable to do this live -- you can check `https://gitlab.archlinux.org/archlinux/infrastructure/-/issues?search=wiki+sso` and also search in `archlinux/archlinux-wiki` if that repo exists).\n2. **Check which MediaWiki version** is running on wiki.archlinux.org and confirm PluggableAuth + OpenIDConnect compatibility.\n3. **Review the infrastructure Ansible** for the wiki role to understand the current deployment pipeline.\n4. **Prototype in a local/staging MediaWiki + Keycloak setup** before touching production.\n5. **Engage the wiki admin team** early about the migration plan, since they will need to coordinate with the user base.\n</output>"}]},"uuid":"37ac9d1b-c8fe-452d-849a-565107d85243","timestamp":"2026-02-20T17:02:29.442Z","toolUseResult":{"retrieval_status":"success","task":{"task_id":"a1e75ed","task_type":"local_agent","status":"completed","description":"Research Arch wiki SSO state","output":"Good, I have the project context.

Any auth disruption is high-impact.\n- **Anonymous editing is already disabled** on the Arch wiki, so all editors have accounts. This makes the migration scope clear but also means every active editor is affected.\n- **Account support responsibility shift** (foxboron's concern): Currently wiki account issues are handled by wiki admins. With SSO, Keycloak account issues would fall to DevOps/whoever manages the Keycloak instance.\n- **The OpenID_Connect extension is mature enough** for production use but should be tested against the specific MediaWiki version Arch runs.\n\n### Recommended Next Steps\n\n1. **Search the infrastructure GitLab** for any existing wiki SSO issues/MRs (I was unable to do this live -- you can check `https://gitlab.archlinux.org/archlinux/infrastructure/-/issues?search=wiki+sso` and also search in `archlinux/archlinux-wiki` if that repo exists).\n2. **Check which MediaWiki version** is running on wiki.archlinux.org and confirm PluggableAuth + OpenIDConnect compatibility.\n3. **Review the infrastructure Ansible** for the wiki role to understand the current deployment pipeline.\n4. **Prototype in a local/staging MediaWiki + Keycloak setup** before touching production.\n5. **Engage the wiki admin team** early about the migration plan, since they will need to coordinate with the user base.","prompt":"Research the current state of SSO/Keycloak integration for the Arch Linux wiki (wiki.archlinux.org, which runs MediaWiki).\n\n1.

How Arch Wiki Auth Currently Works\n\nThe Arch Wiki (wiki.archlinux.org) runs **MediaWiki** and currently uses **MediaWiki's built-in authentication system** -- standard username/password accounts stored in MediaWiki's own database. There is **no SSO integration in place today**. This is confirmed by the IRC conversation in your `todo.txt` where Antiz states:\n\n> \"there's no built-in keycloak integration for aurweb/archweb/wiki\"\n\nArch Linux already runs a **Keycloak instance** that handles SSO for several services (GitLab, Kanboard, etc. under `accounts.archlinux.org`), but the wiki, aurweb, and archweb are not yet connected to it.\n\n## 2. Existing Issues and Discussions About Wiki SSO\n\nFrom the project context:\n\n- **aurweb SSO**: Tracked at `https://gitlab.archlinux.org/archlinux/aurweb/-/issues/54` -- \"[FastAPI] Support SSO authentication\"\n- **archweb SSO**: Related discussion at `https://github.com/archlinux/archweb/issues/152` -- \"Implement 2 Factor authentication\" (SSO via Keycloak was discussed in comments, notably `#issuecomment-583763884`)\n- **Wiki SSO**: Antiz mentioned \"there was some discussion (maybe some started efforts) for the wiki as well, but can't remember where it is.\" This suggests there may be an open issue on `gitlab.archlinux.org/archlinux/infrastructure` or a related repo, but it was not pinpointed in the IRC conversation.\n\nKey concern raised by **gromit**: \"the other hard problem is the migration flows for the already existing userbases\" -- meaning merging existing MediaWiki accounts with Keycloak identities is a nontrivial challenge.\n\n**foxboron** also raised the concern that SSO shifts account support responsibilities from package maintainers to DevOps.\n\n## 3. Available MediaWiki Extensions for OIDC/Keycloak\n\nThere are several relevant MediaWiki extensions:\n\n### a) Extension:OpenID_Connect (Primary Candidate)\n\n- **URL**: `https://www.mediawiki.org/wiki/Extension:OpenID_Connect`\n- **What it does**: Provides OpenID Connect (OIDC) authentication for MediaWiki. It is built on top of the `Extension:PluggableAuth` framework.\n- **Keycloak compatibility**: Yes -- Keycloak is a standard OIDC provider and this extension works with any OIDC-compliant IdP. Multiple production deployments exist using Keycloak + this extension.\n- **Dependencies**: Requires `Extension:PluggableAuth` (version 6.x+ for recent MediaWiki). Both are available via Composer.\n- **Configuration**: In `LocalSettings.php`, you configure the OIDC provider URL, client ID, client secret, and attribute mappings. Example:\n\n```php\nwfLoadExtension( 'PluggableAuth' );\nwfLoadExtension( 'OpenIDConnect' );\n\n$wgPluggableAuth_Config['Arch Linux SSO'] = [\n    'plugin' => 'OpenIDConnect',\n    'data' => [\n        'providerURL' => 'https://accounts.archlinux.org/realms/archlinux',\n        'clientID' => '<client-id>',\n        'clientSecret' => '<client-secret>',\n        'scope' => ['openid', 'profile', 'email'],\n    ],\n];\n```\n\n- **Maintenance status**: Actively maintained (part of the MediaWiki extension ecosystem, authored by Cindy Cicalese / Jason Zhang, maintained by the community).\n- **MediaWiki compatibility**: Works with MediaWiki 1.39+ (current LTS) through the latest versions.\n\n### b) Extension:PluggableAuth\n\n- The framework that OpenID_Connect sits on top of.\n- Provides the auth pipeline hooks, login/logout flow management, and auto-account-creation capabilities.\n- Allows configuring whether local login is still available alongside SSO, which is important for migration.\n\n### c) Extension:SimpleSAMLphp (Alternative)\n\n- If SAML is preferred over OIDC, this extension integrates with SimpleSAMLphp.\n- Keycloak supports SAML 2.0 as well, so this is technically viable.\n- However, OIDC is the more modern and simpler protocol and is what Arch's other services use. OIDC is the recommended path.\n\n### d) Extension:WSOAuth (Alternative)\n\n- Another OAuth2-based auth extension.\n- Less commonly used than OpenID_Connect for Keycloak specifically.\n- The OpenID_Connect extension is the better fit since Keycloak is a full OIDC provider.\n\n## 4. Technical Assessment: What Would Be Needed\n\n### Infrastructure Changes\n\n1. **Keycloak Client Registration**: Create a new OIDC client in the Arch Keycloak realm (`accounts.archlinux.org`) for the wiki. This means:\n   - Client ID and secret\n   - Valid redirect URIs (e.g., `https://wiki.archlinux.org/index.php/Special:PluggableAuthLogin`)\n   - Appropriate client scopes (openid, profile, email)\n   - Optionally, custom mappers if wiki-specific roles/groups are needed\n\n2. **MediaWiki Extension Installation**: Install two extensions via Composer on the wiki server:\n   - `PluggableAuth`\n   - `OpenIDConnect`\n   - This likely involves updating the Arch infrastructure Ansible role for the wiki (probably under `roles/wiki/` or similar in the infrastructure repo).\n\n3. **MediaWiki Configuration** (`LocalSettings.php`):\n   - Load both extensions\n   - Configure the OIDC provider endpoint, client credentials, and scope\n   - Decide on the login policy:\n     - **Dual mode**: Keep local MediaWiki login available alongside SSO (recommended during migration)\n     - **SSO-only**: Disable local login entirely (end goal, but risky during transition)\n   - Configure auto-account-creation and username mapping\n\n### User Migration (The Hard Problem)\n\nThis is the most complex part, as gromit highlighted:\n\n1. **Account linking**: Existing wiki users have MediaWiki-native accounts. When they first log in via Keycloak, the system needs to either:\n   - **Auto-link** by matching email addresses (if emails are verified on both sides)\n   - **Manual linking**: Prompt users to log in with their old credentials once to link the accounts\n   - **Batch migration**: Pre-link accounts by matching usernames/emails in the database\n\n2. **Username mapping**: MediaWiki usernames may differ from Keycloak usernames. The OpenID_Connect extension supports configurable subject mapping (`preferred_username`, `email`, `sub` claim, etc.) but mismatches need a strategy.\n\n3. **Bot and service accounts**: Some wiki edits may be automated. These accounts need to either be migrated or use MediaWiki's bot password mechanism (which bypasses OIDC).\n\n4. **Rollback plan**: Keep local auth available as a fallback during the transition period.\n\n### Estimated Scope of Work\n\n| Task | Effort |\n|------|--------|\n| Keycloak client setup | Small (< 1 hour) |\n| Extension installation + basic config | Small-Medium (a few hours, mostly Ansible work) |\n| Testing in staging environment | Medium (a day or two) |\n| User migration strategy + implementation | Medium-Large (the bulk of the work) |\n| Documentation and communication to users | Small-Medium |\n| Monitoring and post-launch support | Ongoing |\n\n### Risks and Considerations\n\n- **The wiki has a very large user base.** wiki.archlinux.org is one of the most-trafficked Linux wikis. Any auth disruption is high-impact.\n- **Anonymous editing is already disabled** on the Arch wiki, so all editors have accounts. This makes the migration scope clear but also means every active editor is affected.\n- **Account support responsibility shift** (foxboron's concern): Currently wiki account issues are handled by wiki admins.

Archweb OIDC Support (GitHub Issue #284)\nThere is an open issue to add OpenID Connect support to Archweb to allow authentication via Keycloak. The suggested approach uses `mozilla-django-oidc` (https://github.com/mozilla/mozilla-django-oidc), and the issue also documents how to locally set up Keycloak for development.\n\nThe issue details group/role mapping logic:\n- Release Engineering members get Django staff status to allow logging into the Django admin backend. Support Staff are assigned if they belong to specific Keycloak groups like \"Bug Wranglers\", \"Forum\", \"wiki\", \"Security Team\", or \"IRC\". Testers are assigned if they are in \"External Contributors/Archweb/Testers\".\n- The issue notes they should not rely
