This recipe requires the Windows Server 2003 forest functional level.
You want to redefine a class or attribute that was previously created.
To redefine a class or attribute, you must first deactivate it by
isDefunct attribute to TRUE (see
Recipe 10.20 for more details). If you are
deactivating a class, make sure no objects are instantiated that use
the class. If you are deactivating an attribute, make sure it
isn’t populated on any objects and remove it from
any classes that have it defined as part of
After the class or attribute has been deactivated, you can modify
(i.e., redefine) the LDAP display name
lDAPDisplayName), the OID
oMSyntax), and the
schemaIDGUID. The one attribute that you cannot
modify is the common name.
Redefining schema objects is a new feature of Windows Server 2003.
Although you still cannot delete schema objects in Windows Server
2003, you can work around many of the reasons that would cause
you to want to delete a schema object by redefining it instead. Some
examples of when redefine comes in handy includes if you accidentally
mistype an OID
lDAPDisplayName, or no
longer need an attribute you previously created. You can reuse it by
renaming the attribute and giving it a different syntax.
