// $ds is a valid link identifier for a directory server
if (ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3)) {

    echo "Using LDAPv3";

} else {

    echo "Failed to set protocol version to 3";

}
?>

Example 1124. Set server controls

copy to clipboard

<?php
// $ds is a valid link identifier for a directory server

// control with no value
$ctrl1 = array("oid" => "1.2.752.58.10.1", "iscritical" => true);
// iscritical defaults to FALSE
$ctrl2 = array("oid" => "1.2.752.58.1.10", "value" => "magic");
// try to set both controls
if (!ldap_set_option($ds, LDAP_OPT_SERVER_CONTROLS, array($ctrl1, $ctrl2))) {

    echo "Failed to set server controls";

}
?>

To get this to work I had to set the LDAP version to 3 using ldap_set_option. Here is an example that might help: $TheDN = "cn=john smith,ou=users,dc=acme,dc=com"; $newRDN = "cn=bill brown"; $newParent = "ou=users,dc=acme,dc=com"; ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3); @$result = ldap_rename($ds, $TheDN, $newRDN, $newParent, TRUE);

The following flags are valid integer values for the LDAP_OPT_DEREF (as taken from the documentation for ldap_read()): LDAP_DEREF_NEVER (int 0) - (default) aliases are never dereferenced. LDAP_DEREF_SEARCHING (int 1) - aliases should be dereferenced during the search but not when locating the base object of the search. LDAP_DEREF_FINDING (int 2) - aliases should be dereferenced when locating the base object but not during the search. LDAP_DEREF_ALWAYS (int 3) - aliases should be dereferenced always. Example: <?php ldap_set_option($ds, LDAP_OPT_DEREF, LDAP_DEREF_ALWAYS); ?> These are defined in the draft C API (presumably from the original LDAP API). See draft-ietf-ldapext-ldap-c-api-xx.txt included in the OpenLDAP source code distribution.

Luckily you can turn on debugging before you open a connection: ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7); This way you at least can see in the logs if the connection fails...

minusf

it seems that ldap_set_option returns 1 for bogus ldap_connect -ions also. ldap_connect always returns a resource (documented in the comments of ldap_connect) so it is not possible to check if the ldap server is there or alive or what. and because ldap_set_option must be between ldap_connect and ldap_bind, there seems to be no sense in checking the return value. it is a bit strange that ldap_bind is the first function which can really check if a ldap resource is usable because it is the third function in line to use when working with openldap. <?php $connect = ldap_connect("whatever"); $set = ldap_set_option($connect, LDAP_OPT_PROTOCOL_VERSION, 3); echo $set; ?>

As john.hallam@compaq.com above mentioned ,one has to set option LDAP_OPT_PROTOCOL_VERSION=3 ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3); to use the ldap_rename function. However, the ldap_set_option() line has to be written immediately after ldap_connect() and before ldap_bind() statements. Christos Soulios
