Casper FV -forceatlogin?

Valued Contributor III

We're seeing a very small number of Macs that are reacting as if the -forceatlogin switch was used when FV was enabled, has anyone else seen this? Rather than waiting to ask the user for their password at logout, an affected system forces the user to enable at login time or it will not let them log in. Normally this wouldn't be a major concern for me (since I want them to encrypt), but we're seeing a high failure rate with these systems (lost data/requiring a reimage).

We are enabling FV using a Casper WDE configuration (which doesn't even support that option) so I'm not sure how this could be happening.
