We were seeing an "error, client cannot be found" issue with federated sites using oauth2_server and openid_connect_sso that had been reported and believed to be fixed in 8.x-1.x-dev at one point or another. In Drupal 9.1.8 and PHP 7.4.3, oauth2_server version 2.0.0-beta3 the error could be reproduced by:

  • Log into a federated site as a non-admin user - success
  • Logout of federated site - success
  • Click Login again on the same federated site and use the same username
  • Error is generated from oauth2_server/src/Controller/OAuth2Controller.php: "error: Client could not be found"

Based on what I saw happening ... I double checked that we still had this patch → included in the new version and that looks correct.

I also saw this related issue → and gave that patch a go, which worked for us. Anyone have thoughts on this solution? That previous issue was closed as a duplicate but it looks like the patch never made it in.
