How to add LDAP authentication to Docker private registry 2.0?

I was looking and spend much time on many forums to get the working external LDAP connection with my Docker Private Registry, but all I see it is connected with nginx or apache. Is there any LDAP connectivity with Docker private registry without anything else installed on server?

I have installed the Docker Private Registry with certificates and I can push and pull images without any problems. My OS is RHEL7.

Thank You in advance!
