[Samba] Debian patched 3.6.6 winbindd fails.

[G.W. Haywood]

Hi there,

I manage a Samba installation which has been operating very well on
Debian Wheezy for a number of years.  Up until last week I was running
3.6.25, which (as always until now) I compiled myself.  Because of the
large number of changes in the recent security patches, I opted to try
the Debian 'samba' and 'winbind' packages.  I was a little horrified
to find that Debian is still using 3.6.6 but that's mainly why I opted
to compile Samba myself in the first place.

Unfortunately the Debian supplied winbindd exits almost immediately
after starting.  The other daemons start and run without problem, and
are serving files as I write.  The Debian-supplied winbindd 3.6.6 log
contains

Of course the join is OK, and winbindd from 3.6.25 has no problem with it.
I'm currently running winbindd 3.6.25 with the Debian patched smbd and nmbd.
Curiously enough the winbindd from 3.6.6 supplied by samba.org, before the
Debian patches but again compiled by myself, also has no problem.

If there's any knowledge Out There about this issue I should be very
glad to hear it.
