Single Sign-On Active Session Errors

Problem

While attempting to use OAuth-based single sign-on to authenticate, users see the following error:

OAuth authorization request denied due to unexpected active login session for "Closed" User ID: xx

Cause

This error occurs when there is already an active login session for a client in the Closed status. The system detects the conflicting session state and denies the OAuth authorization request.

Solution

To resolve this error:

  1. Go to the Admin Log at Configuration () > System Logs.
  2. Locate any active sessions for the specified user ID and terminate them.
  3. In the Profile tab of the client’s profile, update Status from Closed to either Active or Inactive.
  4. Click Save Changes.
  5. Retry the OAuth authorization request with a new token.
