Description John Klinger 2004-03-12 12:20:57 UTC
With "security=ads" and an openLDAP idmap backend.

We are successfully using Samba in this configuration. However, when AD goes
down or reboots, Winbind loses its connection. In the winbind log, it reports:

  Could not open a connection to TEST1 for \PIPE\NETLOGON

Unfortunately, winbind does not reconnect on its own. The only recovery we have
found is to restart Samba on the Winbind systems.

John,  Is this a result of bug 1195 ?  Can I mark it as a duplicate ?

don't increase the cache time when disconnected

no need to multiply the cache time by 8 when 
the default is 5 minutes already.

John, I think this patch and the one in bug 1195 
will resolve this.  Please reopen if not.

Note that the time between unsuccessful reconnects 
(seq_num == -1 ) is the 'winbind cache time' which defaults
to 5 minutes.  If was 40 minutes between reconnects which 
obviously is not right.  The old setting was an appendage from
when the cache time defaulted to 15 seconds.
Comment 4 John Klinger 2004-03-23 07:42:58 UTC
Verified. This, and the patch in 1195 fix the AD reconnection problems.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
