Extending the schema in Windows Server 2008?

[Nils Löber]

Hi All!

Are there any changes to the way Windows Server 2008 handles schema
extensions? Will existing software that modifies the schema continue to work
or are there additional considerations to look out for?

Or, to put it even broader: Are there any changes in the schema
infrastructure?

I know that W2K8 updates the schema (as does Exchange, and R2 and all kinds
of software), but that is not what I am interested in. I am interested in
changes to the underlying schema technology, e.g. when Windows Server 2003
came along, it was suddenly possible to reuse OIDs of disabled schema
attributes, which wasn't possible in Windows 2000. That kind of change. New
features, or changes in existing features or deprecations of features.

Does anybody know of any changes or has first-hand experience with extending
the schema in W2K8 by whatever means (script, LDIFDE, GUI)?

Unfortunately, searching the web and the newsgroups didn't turn up anything.

I'd be grateful for any kind of advice or for any experiences shared.

Best regards
Nils Loeber

Existing software should continue to work.

Autogeneration of link IDs is now documented in MSDN, so you should probably
start using that if you weren't already. That feature existed in 2003 but
wasn't documented.

There are some interesting new searchFlags values you can set, although
curiously they have not been documented by the MSDN team but are coming in
as community content from the MVPs. These relate to the RODC filtered
attribute set and audit limitations. There is also a typo in the MSDN docs
that is mentioned.

http://msdn2.microsoft.com/en-us/lib...65(VS.85).aspx

I hope that helps some. I'm not aware of any other major changes. For
example, there is still no full schema delete capability.

Thank you, Joe. That information is quite useful.

like Joe said, the extension of the searchFlags attribute property for
auditing and RODC-FAS

another interesting only is that objectClass is now indexed in w2k8 AD. in
w2k, w2k3 it was not indexed
