[Samba] Winbind in 3.6.14 crashes against NT4 DC

[Chris Smith]

Filed as bug 9847:

Customer, in the 3.6.x series, has run 3.6.10 through 3.6.13
successfully. After upgrading to 3.6.14 Winbind crashes and their data
is no longer accessible. Reverting to 3.6.13 brings back stability.

Sorry, could not troubleshoot this during business hours. Can get
whatever is requested after hours. Thanks.
