I was trying to add two RP's (Relying Party ) in ADFS 2.1 for the same customer. They use the same signing certificate in both the applications. But while updating in Windows Server 2012 / ADFS 2.1 I am receiving the below error.
MSIS7613: The signing certificate of the relying party trust is not unique across all relying party trusts in AD FS configuration
This was a condition imposed on ADFS 2.0 and Rollup 3 fixed (rather subdued ) this issue. I thought ADFS 2.1 included the updates in Rollup 3. But surprisingly it did not.
This post (written in Portuguese) suggests a work around which looks a bit intricate. Is there any easier way to get around this error ?
We had the same problem. Was solved by applying this hotfix:
