Hi @Richard Michalek

When you try to sign in to an application that has been set up to use Microsoft Entra ID for identity management using SAML-based SSO, you receive the error: AADSTS70001.

This is because the attribute sent from the application to Microsoft Entra ID in the SAML request does not match the identifier value configured in Microsoft Entra ID for the application: "Issuer"

Make sure that the attribute in the SAML request matches the Identifier value configured in Microsoft Entra ID: "Issuer"

In the Basic SAML configuration section of the SAML-based SSO configuration page, verify that the value in the Identifier text box matches the identifier value displayed in the error. If there is a trailing slash at the end of the url, include that as well.
