How do you reverse engineer a “constructed” AD attribute into its different parts?

Question

Active Directory objects contain some constructed attributes that are made up of other attributes.

Using ADSI Edit, I can open the schema of my particular attribute in question (CN=ms-DS-Principal-Name,CN=Schema,CN=Configuration,...) and look at the schema attributes, but I don't see anything in there that defines how it builds its value. I would like to know how to do this.

Answer 1

The logic for the attribute is hardcoded inside of AD. There's no definition in the schema that defines how the attribute is populated.
