Not 100% sure of 1 and 2 below:

1. When you run smbpasswd as a user, the password is passed to a
running smbd because smbpasswd isn't setuid root and the samba
password db isn't updated.

2. If you have a valid unix username and password and an enabled smb
username with a diffferent password, you can connect to a samba share
with your unix password.

Questions:

A. Why don't you sync unix and samba passwords?

B. If you don;t want to do A above, why not change the samba
password(s) with pdbedit?
