Guest Account can't be enrolled in courses

Ultra Experience, Original Experience
Previously, when an unauthenticated user accessed Blackboard Learn and the "Enable Guest" property was enabled they were associated with the "Guest" account. Instructors were able to enroll this "Guest" account in courses and organizations, circumventing application entitlement handling.
This account is a unique Blackboard System Level account that was never intended to be enrolled. Allowing this account to be enrolled meant possible data exposure to unauthenticated users as multiple un-authenticated users could be associated with the account.
Therefore, in this release we removed the ability for the "Guest" account to be enrolled in courses stopping potential data exposure concerns between unauthenticated users. Existing "Guest" account enrollments will remain and be visible to instructors and administrators so they can clean up these existing enrollments through the user interface.
