When adding a new value to olcSyncrepl to a member of a mmr pool, in order to
configure a new pool member, olcMirrorMode is automatically reset since the URI
of the new olcSyncrepl differs from the olcServerID.  A workaround consists in
explicitly reseting olcMirrorMode to TRUE within the same modify operation.
