Plaintext passwords are not stored on the server. The passwords in smbpasswd
are encrypted. You can't mix and match methods because the encryption is
different from UNIX. Since there are no plain text passwords, you can't get
from one to the other.

I think I heard the complaint once that these encrypted passwords are as
good(bad) as real passwords because they can be used just as they are. Unlike
UNIX, which requires the plain text password, and then encrypts it, this
mechanism requires the encrypted password, and then just uses it. Therefore,
you really want to keep that smbpasswd file private. Am I getting this right?
