[Pkg-samba-maint] Bug#436959: winbind hang & startup problem

[Arno van Amersfoort]

Package: winbind
Version: 3.0.24-6

I have a 2 very strange problems with winbind, and I think they are 
related that's why file only one bug report. The first issue is that 
when my machine boots, right after boot 'wbinfo -D {mydomain}' shows:

Name              : PHYSICS
Alt_Name          : Physics.xxxxxxxxxxxx
SID               : S-1-5-21-1818682373-3371831198-3922779086
Active Directory  : No
Native            : No
Primary           : Yes
Sequence          : -1

Although winbind works, it doesn't make sense as the machine is 
connected to a Windows2003 ADS Server. But the strange thing is that 
when I ie. issue '/etc/init.d/winbind restart' it shows:

Name              : PHYSICS
Alt_Name          : Physics.xxxxxxxxxxxx
SID               : S-1-5-21-1818682373-3371831198-3922779086
Active Directory  : Yes
Native            : Yes
Primary           : Yes
Sequence          : -1

Note that both "Active Directory" and "Native" now say Yes (as expected).

Another problem I experience (and I think it's related to the above 
issue) is that once in a while winbind stops responding, obviously 
causing users/groups not be resolved from the Windows2003 domain. 
'wbinfo -p' then shows:

Ping to winbindd failed on fd -1
could not ping winbindd!

Although winbind is still running (ps -ef |grep winbind):

root      3730     1  0 19:50 ?        00:00:00 /usr/sbin/winbindd
root      3731  3730  0 19:50 ?        00:00:00 /usr/sbin/winbindd

Note that I haven't found a way (yet) to reproduce this problem, so it's 
quite hard to debug. The latter issue is (of course) the real show 
stopper as at that point my users are no longer able to access the 
machine until I issue another /etc/init.d/winbind restart.
