If you want your SAMBA server to be the PDC (which is what you want, as
far as I
can make out), and if you are using NT SP3 or above, then you HAVE to
the smbpasswd file and you have to use encrypted passwords.
I was very reluctant to go down this path myself. However, in practice
is not as big a deal as I expected.
I have also made up a web/cgi interface for users to change their
Using expect, it changes both their unix and smb passwords.
