samba - May 2006 - Second SAMBA Server different NETBIOS alias and shares for ClearCase

I have a SAMBA Server utilizing an LDAP backend for user authentication
and it works great unless I use ClearCase. When ClearCase is used the
compilation time for our code is slowed down to a crawl and the
ClearCase application is rendered nearly useless. As a test fix my boss
wants me to create a second SAMBA server to be used for only the
ClearCase server. 

I don't know if this will work, but I may be able to accomplish my task
if I set the "os level" lower than my primary SAMBA server set the SID
to the same as my existing server. I then change the "netbios alias"
to
"clearcase". I'll then add my views and vobs through either NFS or
SANS
client to the ClearCase SAMBA server. This way if a workstation using
ClearCase needs  to use the \\clearcase\views share it will utilize the
ClearCase SAMBA server not the primary server. All authentication should
remain through my LDAP server since I did not change the SIDs for my
server or user accounts.

If this plan sound feasible please let me know. If it sounds like I may
break my existing architecture let me know. If you have better
suggestions I am looking for any help. 

Thank you for your time,
Patrick Hoferer

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.
