note 23568 added to function.ldap-start-tls

It should be mentioned, that TLS connections for LDAP *REQUIRE* you to use LDAP Protocol version 3. By default, PHP uses Protocol 2. Therefore, if you do not know this, you may be puzzled as to why you get "TLS not supported" error. To get around this, just use ldap_set_option to make the LDAP connection use Protcol 2 (if supported). For example: $ds = ldap_connect($LDAP_SERVER,$LDAP_PORT); if ($ds) { if (!ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) { fatal_error("Failed to set LDAP Protocol version to 3, TLS not supported."); } if (!ldap_start_tls($ds)) { fatal_error("Ldap_start_tls failed"); } // now we need to bind anonymously to the ldap server $bth = ldap_bind($ds); //make your query } -- http://www.php.net/manual/en/function.ldap-start-tls.php http://master.php.net/manage/user-notes.php?action=edit+23568 http://master.php.net/manage/user-notes.php?action=delete+23568 http://master.php.net/manage/user-notes.php?action=reject+23568
