LOGIN.ACCESS(5) 	       File Formats Manual		 LOGIN.ACCESS(5)

NAME
     login.access -- login access control table

SYNOPSIS
     /etc/login.access

DESCRIPTION
     The  login.access	file  specifies  (user, host) combinations and/or (user,
     tty) combinations for which a login will be either accepted or refused.

     When someone logs in, the login.access is scanned for the first entry  that
     matches  the (user, host) combination, or, in case of non-networked logins,
     the first entry that matches the (user, tty) combination.	The  permissions
     field  of that table entry determines whether the login will be accepted or
     refused.

     Each line of the login access control table has three fields separated by a
     `:' character: permission:users:origins

     The first field should be a "+" (access granted)  or  "-"	(access  denied)
     character.

     The  second field should be a list of one or more login names, group names,
     or ALL (always matches).  Group names must be enclosed  in  parentheses  if
     the  pam module specification for pam_login_access specifies the nodefgroup
     option.  Otherwise, group names will only match if no usernames match.

     The third field should be a list of one or more  tty  names  (for	non-net-
     worked  logins), host names, domain names (begin with "."), host addresses,
     internet network numbers (end with "."),  ALL  (always  matches)  or  LOCAL
     (matches any string that does not contain a "." character).  If you run NIS
     you can use @netgroupname in host or user patterns.

     The EXCEPT operator makes it possible to write very compact rules.

     The  group  file  is  searched  only when a name does not match that of the
     logged-in user.  Only groups are matched  in  which  users  are  explicitly
     listed: the program does not look at a user's primary group id value.
