# Description of its configuration file # # (The default config file is "/etc/security/access.conf". This # default can be overridden with a module config argument # 'accessfile='): # # Login access control table. # # When someone logs in, the table 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. # # Format of the login access control table is 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). A pattern of the form user@host is # matched when the login name matches the "user" part, and when the # "host" part matches the local machine name. # # The third field should be a list of one or more tty names (for # non-networked 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; this # even works for @usergroup@@hostgroup patterns. Weird. # # 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. Both the user's primary group is matched, as well as # groups in which users are explicitly listed. # # Alexei Nogin 1997/06/15 ############################################################################
