Adding LDAP authentication to Ansible playbook answer file

Issue

• While following all the official documents for setting up an advance cluster and even simple cluster every time we run the oc installer or the Ansible playbook our LDAP settings files get wiped out of the /etc/openshift/master/master-config.yaml file. Is there a way to add the LDAP config to the answer file or a playbook config set?
• How to set up LDAP authentication in the Ansible hosts file?
