[Samba] Win XP Client with Samba AD - Mapping Shares

[Marco Shmerykowsky PE]

I'm having issues having WinXP client access shares
on my Samba domain.

The user account can authenticate to the network using a
Win10 client.  The win10 client maps the users drives and
allows access properly.

The WinXP client can join the domain & the user can login
on the machine in question.

However, attempting to map a drive using "net use"
results in an error about an invalid user/password
(Error 1326).

I have one other XP box, but not seeing issues there.

Thoughts?
