Logging in with a specific SSO user is currently not possible, error: "The external login information is invalid. (#213)."

Issue Description: Logging in with a specific SSO user is currently not possible. However, a majority of other users can log in successfully. The connection is established through SAML and passes through the ADFS Server. Despite that, an error message appears in the Cloud stating: "The external login information is invalid. (#213)."
