JSI Tip 2645. Schema Administrator requires new registry value name to enable a write operation to the schema?

Management of Schema is restricted to members of the Schema Administrators group.

Additionally, schema modification requires the ability to write to the schema. This is disabled by default.

To enable a schema administrator to write to the schema, use Regedt32 to navigate to:

HKEY LOCAL MACHINE\System\Current Control Set\Services\NTDS\Parameters

On the Edit menu, Add Value name Schema Update Allowed, as a REG_DWORD data type. Set the data value to 1. It is not necessary to restart your server.

NOTE: To disable the schema updates, set the Schema Update Allowed data value to 0.
