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.
dn: 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.
