    Based on the error, the IdentifierUris is not verified in your Azure AD tenant.

    IdentifierUris domain needs to be registered and verified in your Azure AD primary domain or subdomain. Check this guide for steps.

    Thank you for your post!

    Based off the documentation that you're following, it looks like your scenario isn't supported since You must use a domain that you own. For this reason, you cannot use certain well-known domains such as azurewebsites.net or cloudapp.net.


    If you need to purchase a domain using the Azure Portal, you can search for and select App Service Domains -> Select Create. For more info.

    Additional Link:
    Buying a domain with GoDaddy

    Once you purchase the domain you can Add your custom domain name using the Azure Active Directory portal, and re-try following the documentation.

    If you have any other questions, please let me know.
    Thank you for your time and patience throughout this issue.

    I was wondering what the solution is for those domains? If Microsoft expecting to register custom domains know for every little test machine we create? And what about 3rd party setups in this case? We are using quite a lot of these, don´t need to be mentioned that we can´t add the domain to azure as it does not belong to us. I couldn´t find any explanation or solution for that use case. In general I found this change poorly communicated. Is anyone having a solution for this case?
