[Samba] How does a user change his password?

[Michael Barnes]

I see lots about how the administrator uses various tools to administer 
users.  However, if the user just wants to change his own password, how 
does he do it? Or can he?

I'm using tdbsam for the password backend.  Samba 3.0.10.  Users are 
Win98 and Win2k.

Thanks,
Michael
