A. They autopopulate the simple and regular bind settings.
Bind settings require specific administrator credentials (username and password) to connect to the LDAP server, which a generic template cannot provide.
B. They automatically set the LDAP user auto provisioning settings.
User auto-provisioning is a separate configuration option that determines if and how users are created on FortiAuthenticator; it is not controlled by the server type template.
D. They define the connection security and domain authentication settings for each LDAP server you integrate with.
Connection security (e.g., LDAPS, STARTTLS) and server IP/FQDN are environment-specific settings that must be configured manually for each individual server connection.
