[cifs-protocol] Conflicting OIDs

[Edgar Olougouna]

Andrew,

After researching MS-ADA documents, Windows source and various standard sources, I have filed a Technical Document Issue (TDI) against the MS-ADA documents. We are actively working on this issue to determine the best way to address this.

I will be on vacation from 12/16/09 through 12/25/09 inclusively. In my absence, my colleague Hongwei Sun (in the CC) will be my backup for this case.

Best regards,

Edgar

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.

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
