Is there a simple way to configure Docker Private Registry 2.0 with LDAP?
Finally I have used that solution:
https://github.com/tierratelematics/existing-ldap-docker-registry
Had some TLS issues with LDAP connectivity (I used ldaps://) and openSSL should be upgraded on my side (I had 1.0.1 version), but at the end it seems to be an easiest option that is working well, as
https://github.com/cesanta/docker_auth
is not working for me for now.
