[SLL] overcoming NFS group limits

[Ted Stern]

This is more of a general Unix question, but I'm looking for a
solution on a Linux server.

If a user accesses an NFS-mounted disk, NFS supports only the first 16
groups of which that user is a member.

This might seem ample for most small systems, but I'm at a large
company with lots of projects, and due to accounting rules a plethora
of groups were created over the years.

We've done a major group cleanup (which should have been done anyway)
but there are still some users who, because of their involvement with many
projects, have to be members of lots of groups.

So, two questions:

1) Is there any hope that NFS will support more than 16 groups in the
near future?


2) Are there any alternatives to NFS?

3) Are there any network mountable filesystems that have support for
access control lists?  Note that the protocol has to be at least as
fast as NFS because we're supporting multi-GB file access.

Thanks,

Ted
