I have integrated Azure login through ADFS and in ADFS I have a third-party claims provider configured which will do multi-factor authentication.
But after I logon to the ADFS through the claim provider, I configured I get the following error. Could someone help me here.
Request Id: ae31a9f4-d84a-4042-bdb6-f39506a8f200

Message: AADSTS90020: The SAML 1.1 Assertion is missing ImmutableID of the user.
I see for all the users. There is no problem with the same relying party when I use AD to sign-in from ADFS. The issue is present only when the third-party IDP (claim provider) is selected to logon.
There are no issues from the IDP side actually. It authenticates the user and ADFS approves the same and getting redirected to the Azure portal as expected. But azure denies it with the error reported above82662-azure-adfs-relying-party-rules-exported.pdf. Kindly help me here.
