It May not help you here. See my comments at the end.

Not if you edit the registry remotely. There are several ways to do
this. If you have a domain admin account, thne that simplifies things
immensely. Use regedit.exe and connect remotely and import the

Here what I was thinking. It really had more to do with migrating
accounts from an NT PDC than NIS. The migration itself is designed to
work with current Samba / Win95 users or possibility NT domain users.
Could also work if you NT boxes are sending clear text ( and hence the
users are being annoyed by having to enter the password for every first
connection to a different samba server ).
My idea was to have a samba server that was set to "security = server"
and the NT clients had the plaintext passwd enabled. During the login
script to the NT controlled domain, a share would be mapped from the
samba server which would validate against the NT PDC. Since the user had
already logged into the domain, this would succeed and the Samba server
would put an encrypted version of the user's passwd in
This sort of strategy assumes a couple of things.
1. The password is sent in clear text to the samba server. I am
not sure if this is the case using the "passwd server" option.
I am guessing it is.
2. All users already have accounts on the NT PDC.
Make any more sense?
