Is ObjectSID a feature of Active Directory or is it a standard feature of all directories?

Question

Is ObjectSID a feature of Active Directory or is it a standard feature of all directories? Is there an Object Class that provides ObjectSID which can be used in other directory services such as OpenLDAP or ApacheDS?

The value of objectSID - the Security Identifier - is a Windows NT-thing, not a generic directory service-thing.

Version 3.0 (and newer) of the Samba project's LDAP schema contains a fully compatible attribute class called sambaSID, intended to store and display SID's just like the objectSID class.
