+pam_access — PAM module for logdaemon style login access control
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+DESCRIPTION
+
+The pam_access PAM module is mainly for access management. It provides
+logdaemon style login access control based on login names, host or domain
+names, internet addresses or network numbers, or on terminal line names in case
+of non-networked logins.
+
+By default rules for access management are taken from config file /etc/security
+/access.conf if you don't specify another file.
+
+If Linux PAM is compiled with audit support the module will report when it
+denies access based on origin (host or tty).
+
+OPTIONS
+
+accessfile=/path/to/access.conf
+
+ Indicate an alternative access.conf style configuration file to override
+ the default. This can be useful when different services need different
+ access lists.
+
+debug
+
+ A lot of debug informations are printed with syslog(3).
+
+noaudit
+
+ Do not report logins from disallowed hosts and ttys to the audit subsystem.
+
+fieldsep=separators
+
+ This option modifies the field separator character that pam_access will
+ recognize when parsing the access configuration file. For example: fieldsep
+ =| will cause the default `:' character to be treated as part of a field
+ value and `|' becomes the field separator. Doing this may be useful in
+ conjuction with a system that wants to use pam_access with X based
+ applications, since the PAM_TTY item is likely to be of the form
+ "hostname:0" which includes a `:' character in its value. But you should
+ not need this.
+
+listsep=separators
+
+ This option modifies the list separator character that pam_access will
+ recognize when parsing the access configuration file. For example: listsep
+ =, will cause the default ` ' (space) and `\t' (tab) characters to be
+ treated as part of a list element value and `,' becomes the only list
+ element separator. 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.
+
+nodefgroup
+
+ The group database will not be used for tokens not identified as account
+ name.
+
+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
+
+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 : 2001:4ca0:0:101::1
+
+User john should get access from IPv6 net/mask.
+
++ : john : 2001:4ca0:0:101::/64
+
+Disallow console logins to all but the shutdown, sync and all other accounts,
+which are a member of the wheel group.
+
+-:ALL EXCEPT (wheel) shutdown sync:LOCAL
+
+All other users should be denied to get access from all sources.
+
+- : ALL : ALL
