[Samba] Domain reconnection after network outage

[olly]

Hi All,

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
