Only users that are already registered for FileVault 2 at the endpoint will be able
to log on to the system after a restart. In order to add a user to FileVault 2
proceed as follows:
While the Mac is still running, log on with the user you want to register for
Provide the credentials of that user in the dialog Enable Your
Users will be able to log on as easily as if there was no disk encryption
Note: You cannot assign users to endpoints in the Management Center to
allow them to use FileVault 2.
