We encountered this at $FIRM, a lamentable proprietary software concern
that was formerly a fairly decent Linux hardware company.  The 32-user
limit was at the time embedded in both the 2.4.x kernel series and in
glibc.  Attempts to assign group memberships beyond that number just
don't work.

I know that it was being removed from the 2.5.41 kernel code, last year,
in anticipation of its removal from glibc.  I don't know if the glibc 
people caught up with that, or not.

Note:  There are complications for NFS and NIS if group size gets big.
(One might argue that POSIX ACLs are a better solution?)
