Issues with CAS ticket data persisting when creating session

[theryop]

Hi!

I am currently trying to configure rack-cas with a project, with single logout. I have followed the readme instructions, using the rack-cas-generated migration to update my db schema, and have edited my session store initializer to point to the RackCas ActiveRecord session store.

When logging in, rack-cas successfully intercepts the ticket validation request, and creates a session as intended. However, for some reason the cas_ticket data doesn't get saved to the session record, which means that on logout, I am unable to delete the session from the session store.

I can confirm from logs and local debugging that the request from my CAS server does send the TGT correctly, and that the store_session method from lib/cas.rb does receive that TGT and saves it to request.session

Any ideas about what might be preventing the session record to be created without the tgt filled?
