Problems authenticating with Win2k account that has sIDHistory set

We observed the same problem and reported it to Samba-Technical in late April. 
We've also characterized the problem to discover that it has multiple failure
modes depending on how many Global Groups with SID History a user belongs to.

A short term workaround we're using is to lower the security mode to "server"
and set the "password Server" parameter to a stable, low use server.  Not ideal,
but it's working for a few hundred users here.

I've been working with the Samba Team to help get a solution released for the
SID History problem.  I'm hoping something is available soon.
