NAME
     group - group file

DESCRIPTION
     The file /etc/group contains for each  group  the  following
     information:

          group name
          encrypted password
          numerical group ID
          comma-separated list of all users allowed in the group

     group is an ASCII file.  The fields are separated by colons;
     each group is separated from the next by a new-line.

     Because of the encrypted passwords, the group file  can  and
     does have general read permission and can be used, for exam-
     ple, to map numerical group ID's to names.

     During user identification and authentication,  the  supple-
     mentary  group  access list is initialized sequentially from
     information in this file.  If a user is in more groups  than
     the  system is configured for, {NGROUPS_MAX}, a warning will
     be  given  and  subsequent  group  specifications  will   be
     ignored.
