The type of modification can be add or replace, and the values specified in the LDAP modify operation do not matter. The requester must have the "Refresh-Group-Cache" control access right on the nTDSDSA object for the DC.

The following shows an LDIF sample that performs this operation.

 changetype: modify
 add: updateCachedMemberships
 updateCachedMemberships: 1

The effects of updateCachedMemberships are outside the state model. An update of updateCachedMemberships causes the DC to refresh its cache of universal group memberships from a GC server.
