The only advantage that pam_smbpass gives you over the built-in LDAP
methods is that it allows the passwords to be migrated WITHOUT a
password change (successful auth is enough to trigger the migration in a
properly configured PAM setup).
If you are planning to force every user to change their password in
order to be migrated, there is no need to use pam_smbpass are there are
better LDAP built-in tools to accomplish the same thing (that will not
require you to jump through the additional hurdle of importing the
newly-created smbpasswd file to LDAP).
In my case, it was unacceptable to make 10,000 students change their
passwords to get them into the smbpasswd file. What we did (note, we
were actually using smbpasswd at that time, so it was the obvious
choice) is to use the migrate argument (or whatever it is called -- the
docs mention it) in order to migrate them into smbpasswd when they
logged into our lab next. After a few months we were confident everyone
made it in, and we pulled the trigger on using that passdb instead of
the unencrypted use of /etc/passwd.
Is this clearer now?
