samba cluster and nmbd

[Evgeny Privarotskiy]

Hi,

I am trying to find any information about nmbd in cluster environment.
Ctdb project made it possible to run samba cluster. Ctdb's wiki
recommends to configure DNS and WINS with cluster public IP's.
However, it is not clear how does nmbd work in the cluster?
Does it run on single node or there is some synchronization between
different instances?
Please share information if you have it.

 Thanks in advance,
 Evgeny
