Ldap objectSid right format

Hi

In active directory, I want to get objetSid in format :




Unfortunatly, objectSid is in binary and when I send my Ldap request with attribute objectSid, that's return :




with option objectSid;binary in attribute, that give me something better but not enought :



For your information, I use a "software package", based on curl for ldap request (url mode). But because it's a "software package", I don't have many scope, so I absolut need to get the objectSid directly formated in the LDAP request.
