Bug #522907 seems to affect users who use Winbind along with an
OpenLDAP server. These users are experiencing frequent winbind crashes
that seem to de due to a behaviour of OpenLDAP that hadn't been
anticipated by Samba developers.
Upstream Samba developers made a (simple) patch to fix this, which
will be pushed in their 3.3.4 and 3.2.12 releases (FYI, we have 3.2.5
in lenny).
It might be possible that #484235 is also fixed by this patch.
The planned patch is attached.
Would it be OK to upload this to s-p-u?
