FileVault2 does not start after 'next login'

[thomas_moser]

We have a script that enables a policy for FileVault2 'At next login' and triggers a reboot so the user has to login.
No problems with OS X 10.10.x, System restarts per script you login and there is the panel for FileVault you have to log in otherwise you are stuck at the login window. But with OS X 10.9.x. when you login nothing happens but if you log out the panel appears wich asks for your password.
Problem is we want to enforce the encryption, but with the log out the user can cancel the start of FileVault and most users do not 'log out' this much...

Anyone an idea?

The "enable at login" is functionality that is only available in Yosemite. I have a post on this available here:

For Mavericks Macs, the only option is going to be to have it enabled at logout. I have a post discussing how this works in Mavericks available here (please see the Enabling FileVault 2 encryption for one or multiple users section.)
