Search by user objectSid (binary attribute) from windows Active Directory with OpenLDAP API

[Hagai Yaffe <HagaiY@Cyber-Ark.com>]

Hello. 

	I am using the OpenLDAP API version 2.1.22 to get data from windows active directory, I am having no problem with text attributes but now I want to search by a binary attribute, the objectSid attribute. I can get this attribute from the active directory but I can't perform a search by this attribute, is there a different syntax for searching by a binary attribute? Should I encode the objectSid in any way?

this is the ldap debug output of my program:

ldap_search
put_filter: "(&(objectClass=group)(ObjectSid=0105000000000005150000000B75D976E7CBDD7DDBEB0C5097350000))"
put_filter: AND
put_filter_list "(objectClass=group)(ObjectSid=0105000000000005150000000B75D976E7CBDD7DDBEB0C5097350000)"
put_filter: "(objectClass=group)"
put_filter: simple
put_simple_filter: "objectClass=group"
put_filter: "(ObjectSid=0105000000000005150000000B75D976E7CBDD7DDBEB0C5097350000)"
put_filter: simple
put_simple_filter: "ObjectSid=0105000000000005150000000B75D976E7CBDD7DDBEB0C5097350000"  

	Any ideas or help would be great.

	TX.
