[Samba] Winbindd timeout on unreacheable domains

[ww m-pubsyssamba]

Hi All,

	I have a concern with the behaviour of winbindd on startup in a multi-domain environment, in my case a 6 domain AD forest + trusts to 3 NT 4 domains. I've tested startup of winbindd in a 2 domain development environment and found if a trusted domain is not contactable it takes five minutes to timeout before winbindd becomes active (/tmp/.winbindd/pipe is created). 
  If I assume this will be the same behaviour for winbindd in our production environment then if our domain were isolated from the rest of the trusted domains then winbindd would take 45 minutes (9x 5minutes) to become active if we needed to restart a server. Because our domain is on a physically different and separately managed network from the others it is more than possible this type of situation could occur. 45 minutes to startup is obviously unacceptable especially as I hope to deploy Samba 3.x on one of our clusters. And to put this in comparison with a pure windows solution we would have no such issues starting a DC or fileserver in a domain just because it couldn't see any or all trusted domains.

  If I am incorrect please can you put me right on this, if I am correct is it possible that winbindd can be modified to establish connection only with its local domain at startup and start serving data to Samba from cached data for other domains?
