Is there a playbook to update authentication provider in openshift

Issue

• Please advise of playbook to utilize when wanting to update just the authentication provider e.g: from Github to Ldap/AD.
• Although the /etc/origin/master/master-config.yaml can be updated manually, keeping the ansible host file with the updated authentication entries is important in case any playbooks needs to be re-executed.
• Also noticed the /usr/share/ansible/openshift-ansible/playbooks/byo/config.yml can be used but it always seems to want to re-create certificates.
• Is there a way to disable cert updates when running the above playbook or better still, if there is a playbook that just updates the authentication portion.
