The majority of synchronization problems involve the connection state of the external servers and the synchronization of the data between the two endpoints. Make sure PingDataSync can properly fail over to another endpoint or server instance if the connection fails on the highest priority external server.

Another factor in troubleshooting synchronization is determining if the DN and attribute mappings were properly configured and if the information is properly being synchronized across the network. Typical scenarios include checking for any entry failures and mapping issues.


Use the resync tool to validate Sync Classes and data mappings from one endpoint to another. The tool provides a dry-run option that verifies data operations without actually affecting the data.

The following log files are specific to PingDataSync, and contain details about the synchronization processes:

Sync Log
Provides information about the synchronization operations that occur within the server. Specifically, the Sync Log records all changes applied, detected or failed; dropped operations that were not synchronized; changes dropped due to being out of scope, or no changes needed for synchronization. The log also shows the entries that were involved in the synchronization process.
Sync Failed Operations Log
Provides a list of synchronization operations that have failed.
Resync Log
Provides summaries or details of synchronized entries and any missing entries in the Sync Destination.
Resync Error Log
Provides error information for resync operations.
