Integrating Red Hat Identity Management Server (IPA) i.e Cockpit with corporate Windows LDAP server

I am trying to integrate Red Hat IPA server with corporate LDAP server so that only those users can log in to Red Hat Identity Management UI (IPA) which exist in the corporate LDAP. Currently, everyone is using a root account to log in to Red Hat Identity Management UI and console. I searched through the Red Hat documentation but got confused when it said use authconfig ui or ipa-client-install, and they said use ipa-client-install utility, but they have not explained very clearly how to do so. Anyone knows the steps how to do this integration?
