Hi, 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. Thanks, Pravin
