PREAUTH_LDAP is the sister model to PREAUTH_ADMIN. This model is an alternative to LDAP_LDAP for customers with a proxy server setup at their site. For such customers, its use permits a clear migration path to TrueSight Middleware Administrator.
Authentication is handled externally via the proxy server, and authorization requests implemented via LDAP.
