samba - Jan 2006 - winbind authentication fails with STATUS_BUFFER_OVERFLOW

Using samba-3.0.10-1.4E.2 as supplied by RedHat Enterprise 4.  Using
security=ADS mode, and using winbind and pam_winbind to authenticate.  

I was able to sucessfully join the domain, and can enumerate users and
groups.  

Whenever I try to authenticate, it always fails with the status
STATUS_BUFFER_OVERFLOW.
