SYNOPSIS

DESCRIPTION

       The file is the group password file for use with the SITE GROUP and SITE GPASS commands.

       To enable the use of this file, the entry must be made in the configuration file

       This file contains an alphanumeric string, encrypted password, and the actual group name from the file.	Each entry is separated by After a
       user logs in, the SITE GROUP and SITE GPASS commands may be used to specify an enhanced access group and associated password.  If the group

       crypt(3), exactly like in real_group_name is the name of a valid group listed in

       NOTE: For this option to work for anonymous FTP users, the ftp server must keep permanently open and the group access file is  loaded  into
       memory.	This means that:

	      (1)  the ftp server now has an additional file descriptor open, and

	      (2)  the	necessary  passwords  and access privileges granted to users via SITE GROUP will be static for the duration of an FTP ses-
		   sion.

       If you have an urgent need to change the access groups and/or passwords *NOW*, then kill all of the running FTP servers.
