gshadow - shadowed group file
/etc/gshadow contains the shadowed information for group accounts. It
contains lines with the following colon-separated fields:
· group name
· encrypted password
· comma-separated list of group administrators
· 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.
