Learn if there is a limit to the number of users to be cached after authenticating users to a managed FDE preboot window.
Details
There is no limit to the number of users that can authenticate.
By default, only the users in the same group as the device with fixed password would be cached. However, as long as the users belong to the same group as the device in the PolicyServer (except the Enterprise group), they can be authenticated and cached without any issues.
