LDAP Lookup

Is there a plugin out there that can perform LDAP lookups?

There is a third-party filter plugin.

Ya, I saw that but it doesn't look like it's being actively developed and I like to keep our installation on the latest GA release. I was hoping there was a built-in that can be purposed to do the connection. It's actually surprising that the Elastic Stack doesn't have this plugin developed and maintained in house.
