Indeed. In an ideal, theoretical sense, having both a unix and a Samba
password brings no advantages, and plenty of disadvantages. I certainly
wish that we had, years ago, set a standard that if you used the Samba
password for local PAM logins, that we only used Samba passwords.
Sadly, it is used in the default debian config of pam_smbpass (again,
this may not be ideal).
