[Samba] Win2K or Samba Caching?

[Robert Rati]

I have a PDC that is Samba 3.0 setup to talk to an OpenLDAP server for 
authentication, and I was able to get a user to log in to a Windows 2000 
machine on the domain.  Then I tried adding additional users, but none 
of them could log in.  So I tried deleting the admin user from the LDAP 
database, but the user could still log into the Windows 2000 machine. 
Then I tried stopping the LDAP database completely, and while it took 
the Windows 2000 machine a long time to attempt to authenticate, the 
user could STILL log into the machine.  Does anyone know if Windows 2000 
or Samba 3.0 do any user/authentication cachine?  Is there any other 
explanation for this?
