You're welcome.

As root, did you run "smbpasswd" or "smbpasswd <user>"? Because
running smbpasswd as root should update the samba password db.

Check "pdbedit -Lv <user>" or "ls -l /var/lib/samba/passdb.tdb" before
and after running "smbpasswd <user>" as root.

I'm pretty sure that it's a (weird) samba feature but not 100% sure.
But it does explain the behavior of your box.

No time for "man pdbedit" but I think that it's "pdbedit -t -u <user>".
