Good morning Andrew - thanks for your question - I have created the below case for us to track our efforts regarding that. One of my colleagues will take ownership and contact you shortly.

Subject: Conflicting OIDs
MS-ADA3 2.305 Attribute thumbnailLogo has:
However, this OID is allocated, according to http://www.alvestrand.no/objectid/2.16.840.1.1137188.8.131.52.html to Netscape (now Red Hat), and is used for nsLicensedFor.
It appears the official OID for thumbnailLogo is
184.108.40.206.4.1.14220.127.116.11 according to
So far, we have found the following OIDs that are allocated to different names between Microsoft's AD implementation and the official
#MiddleName has a conflicting OID
#defaultGroup has a conflicting OID
#thumbnailPhoto has a conflicting OID
#thumbnailLogo has a conflicting OID
What I want to know is: What is the full list of OIDs that Microsoft uses in Active Directory that have conflicting allocations between AD and either the OID allocation hierarchy or common practice?
This will assist us as we aim for interoperability, as for each conflict, we must manually remap.
In the long term, we would like to see the AD schema documents annotated with this conflict (both as as summary table and on each attribute), and a process put in place to avoid these kinds of problems in future.
