Failed login attempts are not logged when audit global profile is set to None

In 4.11, login events are logged in audit logs. User wants to set global audit profile as None and create customrule for groups to capture login attempts. By setting global audit profile as None, logs are getting captured for other groups but login events are not getting captured

1. Edit APIServer resource:
~~~
$ oc edit apiserver cluster
~~~

~~~
apiVersion: config.openshift.io/v1
kind: APIServer
metadata:
...
spec:
customRules:
    - group: system:authenticated:oauth
      profile: Default
    - group: system:authenticated
      profile: Default
    - group: system:unauthenticated
      profile: Default
    profile: None
~~~
3. Try login to cluster with AD user or kubeadmin user
4. Check audit log if logs are captured
~~~
$ oc adm node-logs --role=master --path=oauth-server/audit.log
