'update encrypted' is the setting, it takes the plaintext password
(checked with PAM or the like) and places it into the encrypted password

Also look at the pam_smbpass PAM modules, that will allow a similar
thing for normal logins, and for pam based password changes.

The registry key is 'allow clear-text passwords', windows will always
send encrypted passwords where negoticated.
