I tried it as user and as root, both the same result.

The connect with the unix password works, but i like to connect with
my samba password.

I know this feature, but i like to have different passwords for the
linux and the samba user.

How can i do that with pdbedit? I know that tool, but i don't know how
to change the password with pdbedit. What's the right parameter for
that? Haven't found that at the man page. Maybe I haven't seen the
wood for the trees? :)
