If you try to log in and out of several different OLD instances, you will pretty quickly start receiving a 500 error HTTP response. Logs indicate that this is due to the lock_dir of the Beaker session library getting way too long. See below. Further analysis indicates that this part of the OLD code is to blame since it just keeps making the lock_dir path longer on each OLD authentication switch!
Acceptance Criteria
Ensure users can log in and out of different OLDs from Dative in prod.
This will probably require fixing the code referenced above so that it removes the bottom-level sub-directory name before appending the current OLD as the new sub-directory name.
