Carefully designing the changes that you make to the Active Directory
schema cannot be stressed highly enough for large corporations or
application developers. Selecting a team of Schema Managers and OID
Managers and creating documentation to accompany and justify changes
will smooth that process. Whether you are a small company or a large
multinational, creating sensible structures should mean that you
rarely make mistakes and almost never have to make objects defunct.
Hopefully we have shown you not only the perils and pitfalls of
modifying the schema but also why the schema is necessary and how it
underpins the entire Active Directory. While you should be cautious
when modifying Active Directory, a sensible administrator should have
as little to fear from the Active Directory schema as he does from
the Windows Registry.
