or. Doing this may be useful on a system with group
    information obtained from a Windows domain, where the default built-in
    groups "Domain Users", "Domain Admins" contain a space.

EXAMPLES

These are some example lines which might be specified in /etc/security/
access.conf.

User root should be allowed to get access via cron, X11 terminal :0, tty1, ...,
tty5, tty6.

+:root:crond :0 tty1 tty2 tty3 tty4 tty5 tty6

User root should be allowed to get access from hosts which own the IPv4
addresses. This does not mean that the connection have to be a IPv4 one, a IPv6
connection from a host with one of this IPv4 addresses does work, too.

+:root:192.168.200.1 192.168.200.4 192.168.200.9

+:root:127.0.0.1

User root should get access from network 192.168.201. where the term will be
evaluated by string matching. But it might be better to use network/netmask
instead. The same meaning of 192.168.201. is 192.168.201.0/24 or 192.168.201.0/
255.255.255.0.

+:root:192.168.201.

User root should be able to have access from hosts foo1.bar.org and 
foo2.bar.org (uses string matching also).

+:root:foo1.bar.org foo2.bar.org

User root should be able to have access from domain foo.bar.org (uses string
matching also).

+:root:.foo.bar.org

User root should be denied to get access from all other sources.

-:root:ALL

A user with uid 1003 and a group with gid 1000 should be allowed to get access
from all other sources.

+:(1000) 1003:ALL

User foo and members of netgroup admins should be allowed to get access from
all sources. This will only work if netgroup service is available.

+:@admins foo:ALL

User john and foo should get access from IPv6 host address.

+:john foo:2001:db8:0:101::1

User john and foo should get access from IPv6 link local host address.

+:john foo:fe80::de95:818c:1b55:7e42%eth1

User john should get access from IPv6 net/mask.

+:john:2001:db8:0:101::/64
