Edit report at https://bugs.php.net/bug.php?id=63299&edit=1 ID: 63299 Updated by: mike@php.net Reported by: php at monona dot us Summary: call to ldap_search returns null -Status: Open +Status: Not a bug Type: Bug Package: LDAP related Operating System: Windows PHP Version: 5.3.17 Block user comment: N Private report: N New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Remove the error suppression operator (@) and you'll most probably see an error message about wrong function arguments.

I have successfully bound to a microsoft Active Directory using ldap_connect and ldap_bind. When I call ldap_search with a null for the forth parameter($attributes) it returns a null while setting ldap_error() to "Sucess" and ldap_errno() to zero. The reason for passing a null for $attributes is so that I can explicity set a limit using the sixth parameter ($sizelimit) and because I want everything passed back, as if I had called ldap_search with only three parameters. Another factor that probably contributes to creating this bug is that if I make the call to ldap_search with just 3 paramters, it returns false with error set to "Operations error" and errno set to 1 so there is obviously something else wrong with the search. I would prefer that either this condition return false and a specific error message if there is something about the null $attributes that is an error or that it return false/1/Operations error because that error is in fact still true or that the documentation be updated to reflect when/why this function can return null/o/success when in fact there is nothing successful about the call. Test script: --------------- <?php // replace xxxxxx with your server name $ad=ldap_connect('ldap://xxxxxx'); ldap_set_option($ad, LDAP_OPT_PROTOCOL_VERSION, 3); ldap_set_option($ad, LDAP_OPT_REFERRALS, 0); ldap_bind($ad); // replace xxxxxx etc. with your base DN $result=@ldap_search($ad,'dc=xxxxxx,dc=com','(objectClass=*)',null,1,10); if(!$result){ die('Could not search AD because '.ldap_error($ad).'('.ldap_errno($ad).')'); } ldap_unbind($ad); ?> Expected result: ---------------- return false ldap_error() returns 'Operation error' ldap_error() errno=1 or return false ldap_error() returns 'Some message about invalid $attributes parameter' ldap_errno() returnd unique error number for above Actual result: -------------- Return value of NULL ldap_error() returns 'Success' ldap_errno() returns 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63299&edit=1
