MS-ADA3 2.305 Attribute thumbnailLogo has:

cn: Logo
ldapDisplayName: thumbnailLogo
attributeId: 2.16.840.1.113730.3.1.36

However, this OID is allocated, according to
http://www.alvestrand.no/objectid/2.16.840.1.113730.3.1.36.html to
Netscape (now Red Hat), and is used for nsLicensedFor. 

It appears the official OID for thumbnailLogo is 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.
