Performing this task requires you to have schema administrator credentials, which are assigned to only the Schema Admins group. By default, only the Administrator account in the forest root domain is a member of the Schema Admins group. You can set permissions for different administrators to manage schema operations, but it is best to limit the number of schema administrators to a single highly trusted administrator in the forest.
