Does anyone have a tutorial on generating self-signed TLS certs for OpenLdap server?

I’m using OpenLdap docker image and trying to create TLS client and server certs. I’m not sure if the process of creating self-signed TLS certs in unique to openLDAP, however I can get the client to authenticate the server but I can’t get the server to authenticate the host. I’m just wondering if anyone has a proper method of generating these types of certificates. Most of the information I can find is for SSL certs, not specifically TLS certificates.

Thanks for any direction or link you could provide.
