samba - Jun 2002 - create_canon_ace_lists: unable to map SID...

I'm running Samba 2.2.4 using security = DOMAIN and username map.  I was
able to join the Samba server to the NT domain.  I can also access the
Samba share from my W2K machine.  I log on to my W2K machine using my
domain account.  I'm having problem adding permission (grant access to
another user) to the file and folder I created.  I get the following error:
  create_canon_ace_lists: unable to map SID
S-1-5-21-702160004-1141857705-123780
4090-1107 to uid or gid.

These users are in the username map file.  Have anyone run into this
problem before?

Thanks,
Jeff
