We use different group names with duplicate gids, putting 60 users in
each group.  This works great in our very old NIS realm that services
several Unixes.  For example,

foo:*:8493:user1,user2,...
g8493-1:*:user61,user62,...
g8493-2:*:user121,user122,...

Some things are complicated slightly, but file permissions work fine.
In /etc/security/access.conf, you have to list all of the group names.
