GSHADOW(5)               File Formats and Conversions               GSHADOW(5)



NAME
       gshadow - shadowed group file

DESCRIPTION
       /etc/gshadow contains the shadowed information for group accounts. It
       contains lines with the following colon-separated fields:

       o   group name

       o   encrypted password

       o   comma-separated list of group administrators

       o   comma-separated list of group members

       The group name and password fields must be filled. The encrypted
       password consists of characters from the 64-character alphabet a thru
       z, A thru Z, 0 thru 9, \. and /. Refer to crypt(3) for details on how
       this string is interpreted. If the password field contains some string
       that is not valid result of crypt(3), for instance ! or *, the user
       will not be able to use a unix password to log in, subject to pam(7).

       This information supersedes any password present in /etc/group.

       This file must not be readable by regular users if password security is
       to be maintained.

FILES
       /etc/group
           Group account information.

       /etc/gshadow
           Secure group account information.

SEE ALSO
