freebsd-dev/crypto/kerberosIV/etc/login.access
Mark Murray 03656ac1b0 Initial import of KTH eBones. This has been cleaned up to only include
the "core" Kerberos functionality. The rest of the userland will get their
own changes later.

# Sample /etc/login.access file read by the login program
#
# 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.
