ADFS Error upon logout (SAML)

Is there any difference between what ADFS and Azure support with respect to logout requests (is there a configuration on the ADFS side that needs to be set, does the SAML request need to include/exclude/get signed/etc. when sending to ADFS vs. Azure)?

    There is generally a configuration to set on the Relying Party Trust in ADFS. A log-out endpoint has to be provided.

    I believe that the logout endpoints are configured correctly but I don't think this is it because I am not seeing those endpoints (the logout ones) being called even.
    And from the ADFS logs, we can observe the following error:

    The verification of the SAML message signature failed.
    Message issuer: XXXXX
    Exception details:
    MSIS7084: SAML logout request and logout response messages must be signed when using SAML HTTP Redirect or HTTP POST binding.

    This request failed.

    Does this help?
