We provide customer with metadata but they insist on for Entity ID and ACS URL. At the end SSO works. Is there a certificate on Azure side involved here? We have customer certificate on ADFS side

    @Abhishek Choudhary ,
    To federate ADFS as SP with Azure AD, we need only the Entity ID and ACS URL. Even if we establish the federation by uploading the metadata only the Entity ID and ACS URL are picked by Azure AD from the metadata.

    On the other side, as Azure AD issues signed token to SPs, a certificate (Public key of the Azure AD's token signing certificate) is needed on the ADFS side. So that, ADFS can decrypt the hash of the signed token to ensure its integrity.
