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

NAME
     login.access -- login access control table

DESCRIPTION
     The login.access file specifies on which ttys or from which hosts certain users are allowed to login.

     At login, the /etc/login.access file is checked for the first entry that matches a specific user/host or user/tty combination. That entry can
     either allow or deny login access to that user.

     Each entry have three fields separated by colon:

     o	 The first field indicates the permission given if the entry matches.  It can be either ``+'' (allow access) or ``-'' (deny access) .

     o	 The second field is a comma separated list of users or groups for which the current entry applies. NIS netgroups can used (if configured)
	 if preceeded by @. The magic string ALL matches all users.  A group will match if the user is a member of that group, or it is the user's
	 primary group.

     o	 The third field is a list of ttys, or network names. A network name can be either a hostname, a domain (indicated by a starting period),
	 or a netgroup. As with the user list, ALL matches anything. LOCAL matches a string not containing a period.

     If the string EXCEPT is found in either the user or from list, the rest of the list are exceptions to the list before EXCEPT.

BUGS
     If there's a user and a group with the same name, there is no way to make the group match if the user also matches.
