No this is not what the password sync code does.
The password sync code allows you to get a password
change request from a Windows box, and use the plaintext
password to then change the users unix password.

But the catch is you have to get a password change
request - changing the password on the NT domain
controller doesn't send a change request to the
Samba server on the NIS master, or vica versa.

Such a thing can be done however, and I have
code embedded in Cygnus's Kerbnet product
that will do such a thing.

I am currently negotiating with Cygnus to be 
able to re-release the relevent code portions 
under the GPL (the problem with Kerbnet is it's 
a crypto product and such has *massive* US export 

Hope this helps,
