Base64 encoded Passwords (i.e. used for windows template deployments) get re-encoded after a call to the built URL is made resulting in Base64 in Base64 encoded passwords.

• create a operatingsystem with hash type base64
• create a machine and set a password
• as long as the machine is in status "build" the root_pass is only encoded once.
• If a call to unattended/built is made, the root_pass is base64 encoded twice.

This is normally not a problem but I think it is not an intended behaviour.
