We might not have been clear in our question. I will try to explain what we
are trying to do.

We have a SAMBA Server (Solaris) utilizing an LDAP backend for user
authentication. The Samba server serves PCs for authentication and it serves
Samba filesystem shares. We want to be able to create a second samba server
(Solaris) that can be a member of the domain and also serves shares to PCs
and only serves shares to PC. The second SAMBA server does not need to be
responsible for PC logging / Authentication.

Is that possible and have can I make that second UNIX server a member of the

I don't think you're being very clear. In Windows terms, you log into a
domain, not a server. It sounds like you want to maintain the same
authentication but split an application off onto a different server to
improve performance. However, it's not clear if you want to use Samba or NFS
to share the files. I'm going to assume that the new server will be
providing file services through Samba.

If you want the ClearCase server to use the same authentication, just make
it a member server in your existing domain. Stop the ClearCase Samba shares
on the old server and start them on the new one.
