NAME

       pam_access - PAM module for logdaemon style login access control

SYNOPSIS

       pam_access.so [debug] [nodefgroup] [noaudit] [accessfile=file]
                     [fieldsep=sep] [listsep=sep]

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 information is 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 conjunction 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
           User tokens which are not enclosed in parentheses will not be
           matched against the group database. The backwards compatible
           default is to try the group database match even for tokens not
           enclosed in parentheses.

       PAM_USER_UNKNOWN
           The user is not known to the system.

AUTHORS

       The logdaemon style login access control scheme was designed and
       implemented by Wietse Venema. The pam_access PAM module was developed
       by Alexei Nogin <alexei@nogin.dnttm.ru>. The IPv6 support and the
       network(address) / netmask feature was developed and provided by Mike
