I'm using Debian testing 2.6.16 #2 SMP i686
I tested downgrade samba to 2.0.14 downloading de package from the stable
release, and it works, but it can't read the tdb file, because is and
older version, then I need to change everybody password, and rejoin XP to
the domain, is a huge work.
Please, I need a hurry solution, this service is vital in my work.
