      * Previously, ServiceAccounts (SAs) could not be used as OAuth2 clients because there were no tokens associated with the SAs. With this release, the OAuth registry client has been modified to anticipate this case and the issue has been resolved. (link:https://issues.redhat.com/browse/OCPBUGS-33210[*OCPBUGS-33210*])

      Description of problem:

          OAuth-Proxy breaks when it's using Service Account as an oauth-client as documented in https://docs.openshift.com/container-platform/4.15/authentication/using-service-accounts-as-oauth-client.html

      Version-Release number of selected component (if applicable):

          4.15

      How reproducible:

          100%

      Steps to Reproduce:

          1. install an OCP cluster without the ImageRegistry capability
    2. deploy an oauth-proxy that uses an SA as its OAuth2 client
    3. try to login to the oauth-proxy using valid credentials

      Actual results:

          The login fails, the oauth-server logs:
