What Goes into Change Cache#
- Attributes that are marked X-NDS_NOT_SCHED_SYNC_IMMEDIATE are added to the Change Cacheas a Slow Convergent or (30 second hold time).
- Attributes that are marked X-NDS_SCHED_SYNC_NEVER are added to the Change Cache which will sync whenever the next EDirectory Synchronization cycle happens but not longer than the N4u.nds.heartbeat-data interval.
- Any other Attributes will initiate an immediate EDirectory Synchronization.
- Priority Synchronization - This process does NOT use Change Cache.
- X-NDS_NEVER_SYNC - Are not synchonized and therefore are never placed in Change Cache
