Re: Question on : Winbindd dumps core in find_builtin_domain() at nsswitch/winbindd_util.c:673

["Har Gagan Sahai" <shargagan@xxxxxxxxxx>]

Hi Volker,

This is happening in our specific Active Directory setup. It is reaching this path finally and overwriting the builtin domain. This is causing the dump later. We have a bug raised in Novell on this issue  (bug #292609, not sure whether you will be able to access this.).

regards,
Har Gagan Sahai

No, very likely that is not changed.

Your patch might fix it, but to me it seems the wrong place
to fix. For S-1-5-32 we should *never* end up in that
routine. How does winbind get there? For internal domains we
should never connect to the network.
