[server:<instance>] stanza
This stanza defines a back-end LDAP server that can be used for federated registries.
All operations to specific branches of the LDAP DIT can be passed through to this back-end server.
You can use multiple instances of this stanza.
[ldap] configuration entries that are not configurable in this stanza use the [ldap] stanza values. For example, "tls-v12-enable".
For Active Directory back-end, you must use an SSL connection (ssl-enabled = yes, port = 636).
