Hello, I've implemented a SAML SSO login to an Azure AD app.
All seems to work fine (the login form is opened, the credentials correctly validated, and the session authorized from the identity provider), but when it returns to ANM app it gives this error:
Oops An item with the same key has already been added. Key: http://schemas.microsoft.com/claims/authnmethodsreferences /login/saml
What can I check to solve?
