Hello Sam,

You (root) must edit the file "/etc/group" to have the user
identified as a member of groups other than the primary one in
the passwd file.
-------- example --------
root:*:0:root,mitch
sys:*:3:root,bin,sys,adm,mitch
games:*:10:root,bruce
staff:*:100:sysman,mitch
--------------------------

Then depending on the operating system BSD, SysV, UniStride, AIX
etc. (trademarked products) the user may need to use the 'newgrp'
command (Sys V) to move from the original group to another.  On
systems with a BSD flavor it is possible to reside in a number of
groups at a time.

In the SysV case 'newgrp' causes in effect a new login.  This
flushes any environment or history that may exist. Our UniStride
while a SysV based OS supports multiple groups.

One thing to double check on your system is the group assignment
rules when a file is created.
