How to use oauth proxy:

Note: when using oauth make sure your user has permission to browse grafana.

• add a openshift user htpasswd htpasswd -c /etc/origin/master/htpasswd gfadmin
• use the HTPasswdPasswordIdentityProvider as described here - https://docs.openshift.com/enterprise/3.0/admin_guide/configuring_authentication.html
• make sure point the provider file to /etc/origin/master/htpasswd.
  or using this example cmd:

  sed -ie 's|AllowAllPasswordIdentityProvider|HTPasswdPasswordIdentityProvider\n      file: /etc/origin/master/htpasswd|' /etc/origin/master/master-config.yaml

• add view role to user oc adm policy add-cluster-role-to-user cluster-reader gfadmin
• restart master api systemctl restart atomic-openshift-master-api.service
• get the grafana url by oc get route
• discover your openshift dashboard.
