SYMPTOMS
If a Directory Synchronization (Dir-Sync) requestor postoffice is deleted from the server's list of requestors after a Dir-Sync cycle has completed, and is then added back into the list, the requestor does not process updates from the server.



CAUSE
In the first Dir-Sync cycle after requestor installation and server registration, an Import request is assumed. The Import synchronization (sync) is incremented to one (1). This Import sync is recorded at the requestor. The Import sync is incremented for each Import request received from a requestor.

When the requestor is registered at the server, all syncs are initialized to zero. When the already active requestor requests updates, the server responds with a list of updates and also includes the Import sync, now equal to zero. The requestor receives the updates but notices that the Import sync is less than its recorded value and rejects the updates as old Dir-Sync mail. There are no warnings to indicate the rejection; this is part of the fault tolerant design.



RESOLUTION
The server assumes an Import request if all syncs are zero.

If the server deletes and then adds a requestor registration, then either:


 * The requestor's administrator must submit an Import request -or-


 * The server administrator must give the requestor admin a manual resync file (RESYNC.GLB)

Because the server does not report any error, the requestor administrator should note that the DIRSYNC.LOG reports zero updates received for many cycles, even though updates have been submitted.
