Identifying all non-standard or custom attributes in your Active Directory schema

Hi guys,

I hope you are all well and can assist.

Our company has, over the years, defined custom attributes in the Active Directory schema.

However, no documentation is available ad to what these are.

As we are looking at upgrading our domain controllers to 2012, i want to identify any custom attributes that have been defined.

Any help greatly appreciated.

Thank you.

Not an easy script to do this one, takes some work but it is doable.  The Microsoft AD team wrote a blog entry for this exact issue

http://blogs.technet.com/b/askds/archive/2009/01/20/determine-applied-schema-extensions-with-ad-ds-lds-schema-analyzer.aspx

exact some procedures in a TechNet magazine article

I suspect John used the DS blog entry to write his article

Thanks

Quick add-on I don't want to make it sound like John plagiarized...but the DS teams article was in January and the TechNet magazine in April.   We all use the DS team blog :)

Thanks
