"smbpasswd <user>" works for me as root so no idea except maybe doing
so as the samba admin user if you have a different one.

Check whether you have libpam-smbpass. Its function's to synchronize
the samba password with the unix password when you log in to a box and
they are different.

Without libpam-smbpass, I'd be more inclined to call this a bug but,
if this is the case, I'd have to read the developers' rationale first.

Thanks for the correction. My memory of the command was partial, your
post reminded me that it should be "echo -e "test\ntest\n" | pdbedit
-t -u <user>".

I've just tried it though and it failed so the article or post that
I'd read had more to it than that. I've tried it with debugging turned
on and it throws off errors about group maps and RIDs that I can't
look into now.

You could also look into changing the password with "net" - something
like "net rpc password..." but I can't look up the proper syntax at
the moment. I'm sorry about the incomplete help... :(
