In rails 4 I am throwing 401 when a user tries to access a protected resource, and it redirects me to login as I expect. I already have a valid session with the server open in the browser I'm using, and the server is backed by CASino. The server is responding with a ticket before the deadlock.

In the rails server log I see this bit of relevant information along with this stack trace which shows after about 2 minutes:

Completed 401 Unauthorized in 54ms (ActiveRecord: 2.2ms)
rack-cas: Intercepting 401 access denied response. Redirecting to CAS login.  CACHE (0.0ms)  SELECT "sessions".* FROM "sessions" WHERE "sessions"."session_id" = '6648cc0dfeedcf5c36f1d93465e10886' ORDER BY "sessions"."id" ASC LIMIT 1

Additionally, if I log out on the CAS server, and then repeat this process in my app using rac-cas, I get this:

Sorry for not getting to this for a while. I was out of commission with an injury when you posted this issue. Are you still having this problem?

Sorry for not seeing your reply until you closed this, I in fact gave up, and went with another single sign in mechanism given I had the flexibility and couldn't make this work. Thanks though.
