I noticed that just after I wrote this message. =)
I got that info from something related to the samba-tng branch, which
has implemented the 'P' option.
Unfortunately, on further analysis, TNG's P option isnt what I was looking
for after all. The server simply checks that users ACL's to see whether
it is allowed to update the password for that user, not send a message to
the client that it is not allowed to change the password.
Nevertheless, if this is desired functionality (while not for myself) it
wouldnt be too difficult to apply this to Samba's HEAD tree, which I'm
willing to do if you think that this "feature" is a good thing.

I'd be happy to hack on it a bit, however I'm unsure by what mechanism
(rpc call?) this is sent to the client. I'll look over the code some and
see what I can do.
