- # 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. Only groups are matched in which users are explicitly
- # listed: the program does not look at a user's primary group id value.
