After enabling SSO in our Clarity SaaS environment, some users are unable to log in despite being authenticated by our IDP (Azure).
The error '400 Login Failed - 400 Bad Request Error Code - GENERAL_NONSUCCESS' is seen when attempting to log in to Clarity.
Release : 16.0.3
The user record in your user directory is missing some attributes that are required (firstName, lastName, Email). These need to be sent by the IDP.
Ensure that the required attributes (firstName, lastName, Email) exist for the user in your user directory (e.g. Azure).
After setting the required parameters in the directory, the user should be able to login successfully.
See the Customer Setup section in the Federated SSO Implementation documentation.
