Implementing SharePoint 2010 and CA SSO Integration. There are two different user directories(usertype1 and usertype2), sharepoint created two separate Trusted Identity Providers(TIP) for each user directory. Can't use common TIP because user directories have unique user identifier. Now if we make TIP of usertype1 as default in sharepoint, we're unable to authenticate usertype2. Right now, we have disabled the default TIP in sharepoint, so now Sharepoint throws a credential selector login prompt where you have to choose the appropriate TIP for the corresponding usertype. Able to authenticate both usertype1 and usertype2. But this is just a work around, how do we make it work with two TIPs by selecting one of it as Default ?
