AADSTS75005: The request is not a valid Saml2 protocol message.


  • I'm integrating Azure AD with ZenDesk using the instructions here -

    Everything goes well until I actually try to login ZenDesk. The browser returns - 

    We received a bad request.
    Additional technical information:

    AADSTS75005: The request is not a valid Saml2 protocol message.

    I'm pretty sure the authentication is making it from Azure AD to ZenDesk and getting processed because during some test logins while setting it up the Azure response was including information it was getting From ZenDesk. 

    I've checked on Google but all the answers seem to involve going into the code that's generating the requests and of course in Azure AD I don't have access to that.

    I've already deleted and recreated once with no luck.

    Any ideas on a solution or how I can get more diagnostic information?

  • If you could change the setting on the Zendesk App side to accept UPN (userPrincipalName) instead of eMail attribute for the SAML Token ?

    And if you still face issues, we would recommend to open a Technical Support Ticket for deeper investigation as we would require sensitive information from your end like your Subscription and Tenant details.
