samba - Dec 1998 - How to sync /etc/smbpasswd with /etc/passwd ?

While we do sync our /etc/passwd whenever /etc/smbpasswd is changed via the 
Samba sync option that does not seem to be possible the other way round:

I just want a /etc/smbpasswd generated from my /etc/passwd with the correct 
passwords as used for the UniX login...
Is that possible ?

No!

It is not possible to confert the encrypted /etc/passwd passwords to 
encrypted /etc/smbpasswd passwords without knowing the clear text 
password.

This sounds like a candidate for some sort of user-friendly client, 
perhaps a cgi that one could ask a user to invoke through a web page, 
then generate the encrypted string which would be dropped into the 
smbpasswd.  It's exactly the thing that is lacking in many Unix server/
PC client applications, particularly in database applications.

On a somewhoat related note, is there a way to cause Samba to recognize 
that the user has been authenticated so they don't have to enter their
password a second time at login time when they mount the Samba drive?
Or is my configuration lacking (highly likely!).
