Cannot login Platform UI with CloudPak administrator username

You might not be able to login Platform UI with the updated CloudPak administrator username in foundational services v4.6.4.

Symptoms

Error 401 is displayed on screen.

Workaround

Onnboard the CloudPak administrator username (cpadmin) to Platform UI 4.8.x:

1. Obtain the default Platform UI admin password.

    oc get secret admin-user-details -o json | jq -r '.data.initial_admin_password' | base64 -d && echo
   

2. Obtain Platform UI access token for default Platform UI admin.

    POST: https://<zen_instance_url>/icp4d-api/v1/authorize
    {
      "username": "admin",
      "password": "<zen-admin-password>"
    }
   

   Where, zen-admin-password is the default Platform UI admin password that has been generated in Step 1.

   For more information, see Using Authorization: ZenApiKey token.

3. Add cpadmin to Platform UI with the bearer token that has been generated in Step 2.

    POST https://<zen_instance_url>/usermgmt/v1/user
    {
      "username": "cpadmin",
      "displayName": "cpadmin",
      "user_roles": "['zen_administrator_role']"
    }
   

cpadmin is now onboarded to Platform UI 4.8.x and can perform Platform UI administrative actions.
