[Samba] Domain reconnection after network outage - Repost

[olly]

Hi All,

Sorry to ask the question again, but I got no response last time, and 
wondered if there was any experienced people watching the mailing list 
today - My question was...

 We have a Samba server connecting to a Windows 2000 Domain controller for
 authentication purposes using windbind. We have had a couple of network
 outages recently and the other servers, which are Windows 2000 member
 servers seem to resume normal authenication when the network returns, but
 the Samba server does not recover until samba is restarted. We have had 
this
 problem when the domain server was down for maintainence, so it is not
 specifically related it the network interface going down.

 Is this behaviour limitation of samba, or is there an option I can set to
 continue retrying, or is it a bug? Is there a workaround? Any information
 would be useful. We are using Samba 3.0.11 suse 9.0 packages from 
samba.org.
 Please find at the bottom of the email the last few log entries in case it
 is of some use.

 Thanks in advance,

 Olly
