Single Sign-On Closed User Errors

Problem

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

Single Sign-On authentication denied for "Closed" User ID: xx

Cause

WHMCS requires the client status to be Active or Inactive to perform single sign-on authentication. This error occurs when the client account has a Closed status, which prevents single sign-on access.

Solution

To resolve this error:

  1. In the Profile tab of the client’s profile, update Status from Closed to either Active or Inactive.
  2. Click Save Changes.
