[Samba] AD admin account being locked by Samba?

Hi all,

I've recently used Samba to add a Red Hat Linux machine to an active
directory domain.

In order to do this I used:
net ads join fully.qualified.domain.name -U my-admin-account

...and then was asked for (and entered) my password...

The Samba share has been working great, as has authentication via Active

The only trouble is that I used my own admin account to join the machine
to the domain.
This account has a forced password reset on it, and since I last changed
my password, the account keeps getting locked.

My Active Directory savvy colleagues have used various tools to track
this down to the afore-mentioned Red Hat box.
It appears to be trying to do something with my old password - and thus
locking my account out!

The Samba share continues to work regardless - it's just that I can't
use my admin-level account, which is making life difficult!

We're planning to work around this by creating an admin-level account in
Active Directory specifically for the purposes of joining Linux boxes to
the domain; but I'd like to know what is going on here regardless.

I thought that once you had Kerberos ticket and had joined the domain,
the admin account was finished with?

What might Samba doing with my Active Directory admin account?

Many thanks,
