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:

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
1.3.6.1.4.1.1466.101.120.36 according to

http://tools.ietf.org/html/draft-ietf-asid-schema-pilot-00


So far, we have found the following OIDs that are allocated to different names 
between Microsoft's AD implementation and the official
allocations:

#MiddleName has a conflicting OID
2.16.840.1.113730.3.1.34:1.3.6.1.4.1.7165.4.255.1
#defaultGroup has a conflicting OID
1.2.840.113556.1.4.480:1.3.6.1.4.1.7165.4.255.2
#thumbnailPhoto has a conflicting OID
2.16.840.1.113730.3.1.35:1.3.6.1.4.1.7165.4.255.10
#thumbnailLogo has a conflicting OID
2.16.840.1.113730.3.1.36:1.3.6.1.4.1.7165.4.255.11

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. 

Thanks,

Andrew Bartlett
