I've used it without SSL to quickly throw up a CAS instance to test.
However, as you said, its not very secure that way. And should never be
deployed in production like that.

 I hasten to note that there's a reason the Yale Java CAS client has a
hardcoded check that the URLs it is using to communicate with CAS are SSL
secured -- performing the CAS protocol over insecure channels is not secure,
introducing the potential for man-in-the-middle attacks.

I don't understand the appeal in turning off SSL.  SSL is core to the
security of the CAS protocol and to the concept of a CAS server as a trusted
intermediary.

You can deploy the CAS Server without SSL and it will function fine. The
only change would be:

1. In the cas-servlet.xml, the two cookie generators need the "secure"
property set to false.
2. If you plan on doing proxy callback to clients without SSL, the
HttpBasedServiceCredentialsAuthenticationHandler needs to be configured to
allow non-https urls.  Its a property on the handler.

I believe that is everything for the server.  On the clients, it depends
on the client.  For the Yale CAS Client, there is a hardcoded check for
https that would need to be removed.
