Today, I'm going to cover CockroachDB Active Directory integration. Under the covers, Cockroach utilizes GSSAPI. Today, Cockroach only supports user mapping. It does not support user sync between AD OU to a Cockroach role.
My lab environment consists of an AD controller running Windows Server 2016 as a VirtualBox VM and a Vagrant VM with CentOS 7 hosting CockroachDB. The VMs share a host-only network. This was critical in my setup so that my Cockroach node could interact with AD on port 88.
