Usernames can contain all kinds of characters that are not allowed in resource names. Hash the name instead and use hex representation of the result to get a usable identifier.

    1. log in to the web console configured with a login to a 3rd party OIDC provider
    2. go to the User Preferences page / check the logs in the javascript console
    

The User Preferences page shows empty values instead of defaults.
The javascript console reports things like
```
consoleFetch failed for url /api/kubernetes/api/v1/namespaces/openshift-console-user-settings/configmaps/user-settings-kubeadmin r: configmaps "user-settings-kubeadmin" not found
```

   I am able to persist my user preferences.
