[Samba] Laptop users as domain members; profiles

For the record, you are right.  I have tested logging on to the domain with
cached credentials and it also works with just a local profile.  Of course,
with either roaming or local profiles at least one logon to the domain (when
actually connectied to the domain controller) is required before cached
credentials are available.

I am still a bit confused by the security policy - "number of previous
logons to cache (in case domain controller is unavailable)".   The knowledge
base article -


seemed to also indicate that this puts a limit on the number of times cached
credentials can be used.  Yet,  I set it to two and was able to logon to the
domain (while disconnected from the network) 13 times before I decided that
was good enough for me.  Seems there is no real limit.  Maybe this just
applies when a Windows Server is used as PDC.
