How to configure ADFS 2.0 as SP and CA SiteMinder as IdP

We want to configure ADFS 2.0 as SP and CA SiteMinder as IdP using SAML 2.0. In ADFS 2.0 we have a test application which is deployed using WIF.

We have configured both the things correctly. However, while testing the federation it gives 2 options of selecting the Identity provider correctly. However, after we enter the credentials we get internal server error as message.

Any help would be highly appreciated.开发者_JAVA技巧
