The requester must have the "Update-Schema-Cache" control access right on the nTDSDSA object for the DC or on the root of the schema NC. After the completion of this operation, the subschema exposed by the server reflects the current state of the schema as defined by the attributeSchema and classSchema objects in the schema NC.

The type of modification can be add or replace, and the values specified in the LDAP modify operation do not matter. The following shows an LDIF sample that performs this operation.

 changetype: modify
 add: schemaUpdateNow
 schemaUpdateNow: 1

The other effects of schemaUpdateNow are outside the state model. An update of schemaUpdateNow causes the in-memory cache of the schema to be recalculated from the copy of the schema stored in the schema NC.
