How to configure Liferay login portlet to function as a CAS gateway

We've configured Liferay to use CAS. However, it only works when you click the sign in link in the top right. The standard login portlet where you enter your username/passwo开发者_开发技巧rd does not go against CAS. We would like to have this portlet use CAS, which I'm assuming would be via the proxy method.

Any ideas on how to accomplish this? I figured this would be an out-of-the-box sort of functionality once you enable CAS within Liferay, but it appears to not be.

Thanks!

One of the main advantages for using any SSO solution (like CAS) is that the single applications don't ever get access to your password - it's solely in the realm of the SSO solution to handle this.

My advice is to remove the standard login portlet from the page instead of changing it to go to CAS. You can add a link to the CAS login page if you want, but you don't need the login portlet for that.
