Transfering passwords from Unix to NT

[SI-Gaetan Boudreau]

Hi fellow Samba Admin.

What is the best way to transfer the password file from Unix to NT.

Let's say we have Samba running with security=server and encrypted=yes 
and the encrypted passwords are in the smbpasswd file.  The 
authentication server is a Unix machine.

If we want to add an NT server (PDC) on the network and make it 
authenticate with "password server = NTmachine", is there a way to 
transfer all the users passwords from smbpasswd on the Unix machine to 
the SAM on the NT machine.

Is it easier to migrate from clear text password ?
Because we are still in that mode for now.  Which brings another 
question.  Is there a way, other than having each user set is encrypted 
password with the command "smbpasswd", to switch from clear password to 
encrypted mode ?
Is storing the passwords in smbpasswd mean that the user can have a 
different password for Unix and SMB ?

Thank you for your time.
