Description Takao Yoshihara 2012-05-21 15:04:54 UTC
Hi all,

I use Samba-3.4.17 which is rpm-built from original tar ball on Scentific Linux 6.2 (i686).

I established trusted domain relationship between Samba BDC and AD (domain function level is Windows Server 2003) and Winbind often hung up showing the following error:

sorry for the delayed answer. This is not really helpfull because no debug symbols are there. 3.4 is also out of date now. If you still see this problem with 4.0, please reopen this bug and run samba with debug symbols compiled in or installed from debuginfo package. Thanks ...
