LdapV3Ext is the frozen child “LdapConfig” or “ActiveDirectoryConfig” container under the LdapV3ADUserService or LdapV3UserService (LDAPv3 support) and contains various properties that specify the LDAP attribute and connection methods. In addition, a child “authenticator” container specifies authentication parameters for connection to the LDAP server.

Although intended for LDAPv3 support, these LDAP user services are also backwards-compatible with LDAPv2 systems. However, Kerberos authentication is not supported in this case.
