Re: CAS and SSL

[Andrew Petro]

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. Andrew Scott Battaglia wrote: 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.  -Scott On 5/1/07, webzo <[EMAIL PROTECTED]> wrote: I have some questions about CAS and SSL.   What parts of CAS actually require SSL? The client (CASFilter) seems to require that the validateUrl callback be "https" rather than "http". How about the server side? What parts there require SSL be used? The reason for these questions are that I am trying to find out if there is a way to use CAS without installing certificates. I know, Scott, Andrew and others on this forum have stated many times that CAS should be used with SSL. Still, I am in a situation where I need to use CAS with out any certificates being installed (because it is going to be hard to install it on the system in question). I saw a message ( http://tp.its.yale.edu/pipermail/cas/2006-April/002652.html) where the implication seemed to be that SSL can be disabled with code changes. Can someone (Scott?) please provide more information on how to do this?   Thanks Ahhh...imagining that irresistible "new car" smell? Check out new cars at Yahoo!
