passwd The passwd element contains the group's password in an encrypted format. Often, for example on a system employing "shadow" passwords, an asterisk is returned instead.
gid Group ID of the group in numeric form.
members This consists of an array of string's for all the members in the group.


Version Description
4.2.0 Prior to this version, members was simply an integer representing the number of members in the group, and the member names were returned with numerical indices.
