CAS 1 and CAS 2

[Alex Johnson]

Hi Andrew,Thank you for your quick answer. I am kind of confused with the proxy authenticationYou mentioned CAS 2 is for proxy authentication. In my CAS 2 configuration, I use Cas20ProxyReceivingTicketValidationFilter in my web.xml. You confirm that I am in CAS 2 architecture. I want to know if I am using proxy authentication when I use Cas20ProxyReceivingTicketValidationFilter in my web.xml.Also, if I am not in a portal environment, how do you explain CAS 2 benefits in a normal situation. For example, I have one or more than one Tomcat servers and several applications in each server.
How this differentiate CAS 1?Thanks, Alex

CAS 1: Basic authentication; user requests service directly and receives itCAS 2: Proxy authentication; service requests another service on behalf of user and receives itAn example where this is useful: your company / organization has a portal that everyone logs in.  If you expect the portal to deliver your email for you, then it is requesting your email on behalf of you.  If the email server is CAS protected, then this would never work, so the portal must request your email on your behalf.I wouldn’t say proxy authentication is for a portal environment; it is useful whenever you want build some manner of web service.On 8/11/08 5:10 PM, "Alex Johnson" <sheep123 at hotmail.com> wrote:
 Hi, Bother to bother all the experts. After I successfully configured  both CAS 1 and CAS 2, I am still kind of confused with the benefits by upgrading CAS 1 to CAS 2. It seems to me that there is no difference between CAS 1 and CAS 2 in the front end. Using CAS 1 or using CAS 2 configuration can produce the same output. If so, why bother to upgrade to CAS 2?? It seems to me that by distinguishing CAS 1 and CAS 2, it's just the configuration difference and use most current version client, right?? It seems to me that CAS 1 is designed for SSO and CAS 2 is designed for a portal environment, right? If you can tell me more about what the advantages/benefits/differences are by upgrading CAS 1 to CAS 2, I will be very appreciated it Thanks,  Alex
