Man Pages Index

DESCRIPTION
       /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.
