ldap_set_option

As john.hallam@compaq.com above mentioned ,one  has to set option LDAP_OPT_PROTOCOL_VERSION=3ldap_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

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...

If you want to disable the TLS cert check (e.g. because you are doing an SSH port-forward, and ldaps is pointing to localhost), then you must invoke:ldap_set_option(NULL, LDAP_OPT_X_TLS_REQUIRE_CERT,0)*before* calling ldap_connect()If you try: $ds = ldap_connect(...)ldap_set_option($ds, LDAP_OPT_X_TLS_REQUIRE_CERT,0)then the option won't actually take effect, and the certificate will be checked anyway, and a TLS failure will happen..

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:<?phpldap_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.

PHP 7.1 added support for configuring the LDAP CA/Cert environment directly, rather than relying on the environment variables. I noticed that a lot of people are having trouble getting this to work.The correct way is:$ds=ldap_connect("ldap.google.com");  ldap_set_option(NULL, LDAP_OPT_X_TLS_CERTFILE, "/path/file.crt");ldap_set_option(NULL, LDAP_OPT_X_TLS_KEYFILE, "/path/file.key");ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3);ldap_set_option($ds, LDAP_OPT_REFERRALS, 0);ldap_start_tls($ds);...ldap_close($ds);

I have the following code, but you do not rename the cn, that may be?    $TheDN = "cn=Nombre,ou=Addressbook,dc=axia-ldap,dc=net";    $newRDN = "cn=bill";    $newParent = "ou=Addressbook,dc=axia-ldap,dc=net";    ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);    $result = ldap_rename($ds, $TheDN, $newRDN, $newParent, TRUE);

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);

it seems that ldap_set_option returns 1 for bogus ldap_connect -ions also.ldap_connect always returns a resource (documented in thecomments of ldap_connect) so it is not possible to check if theldap server is there or alive or what.  and because ldap_set_optionmust be between ldap_connect and ldap_bind, there seems tobe no sense in checking the return value.it is a bit strange that ldap_bind is the first function which canreally check if a ldap resource is usable because it is the thirdfunction 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;?>
