Hello there,
I don't know if it is ment to be like this but changing a users password as 
root doesn't initiate the synchronizing to the passwd if unix sync is turned on.
While this works fine at the user's end the administrator cannot reset a 
password in one move, he has to first change it in passwd and then in 
smbpasswd. That of course could be handled externally by a script, but I 
thought it would be more complete to work directly from within samba.
Keep up the good work!!
Best Regards
Frank Mayer
