Hi,

When making NIS I have received this problem for quite along time but 
without seeing any problems, what does it mean is there a limitation or 
not ?


bash-3.00# /usr/ccs/bin/make
/usr/sbin/mknetid: mila's groups exceed 16

The NFS protocol (at least versions before 4) has a limit of 16 groups, 
so being in more groups than that will not work very well with NFS.  I 
am not sure what the local limit is, but it may also be 16, on the 
grounds that there's not much point in making it some large value and 
having things break mysteriously over NFS.

If you NEVER plan on using NFS, you can have a user be a member of up to 
32 groups.  AFAIK, there's no way to have a user be in more than 32 
groups.  If you need that level of granularity, use ACLs.
