File group ownership is tracked by numeric group ID, so you'll need a
user group on the server and clients which has the same numeric ID on
each system, and to which all the users belong.  Even if this means
creating a new user group on each system and manually adding the users
to it. 

In /etc/group, you can define a list of members for each group, even
if that group is not each user's primary group

users:x:100:steve,phil

It may be worth your while investigating NIS as this is typically used
alongside NFS to synchronise logins and file access.
