SSL Problems? IP x DNS -> Localhost

[Paulo Cheque]

Hi, I am trying to start use CAS with Tomcat 5.5.x.

- I create a AuthenticationHandler that implements
AuthenticationHandler interface.
- I have configured deployerConfigContext.xml to find my implementation.
- Make a war file and deploy it.

When I put a valid login throw that exceptions above.
I am thinking the reason is "Certificate for IP" because I am working
with localhost and certificated has problens with IP. Am I rigth?

Is there any mode to test my CAS with localhost?

Thanks in advance!
Paulo
