Establishing netbios aliases involves a whole lot of coordination -- 
only one system can be configured to be using the netbios alias at a 
time.   Besides, we're trying to avoid the netbios name issues 
altogether by stipulating FQDN-based UNC resource references.

The key in our system is to be able to move a role/service around by 
moving an IP address between servers.  The servers would be 
configured with multiple IP addresses -- their fixed/static, base 
address and the role address that can be activated on a machine as needed.

This method continues to work well under Samba 3.0.9/3.0.10 on our 
W2K AD implementation.    However, our workup with Samba 3.0.22+ and 
a W2K3 AD, with the samba servers being more integrated results in 
auth failures when we try to employ this methodology.

Given the similarity of our paradigm to the CNAME-based paradigm that 
Roy Mann asks about, I think Jerry's suggested solution for Roy migh 
apply to my situation as well.   However, I need to find out the 
constraints and limitations of this "fix"...
