Synchronization failed for domain:
UserName:[superuser-1191748921] [#100008] Error processing crawl notification: Directory synchronization task failed , Caused by [#430256] Unexpected error: Error in doing Directory synchronization - Error in doing Directory synchronization - Please check the job log for errors.
This is typically permissions related issue. By default, the Domains to crawl has a blank account and password. In this configuration, it automatically uses the account listed in the EsaApplicationservice. In some situations, adding the same account as in the EsaApplicationservice to synchronize the domain can cause the Active Directory synchronization to fail.
In the Appliance, from the System | Directories and Servers | Active Directory tab,
1. Delete the domain using the Trash can icon to the right of the domain in question.
2. Re-add the same domain by clicking on the Add Domain button
3. Leave the account and password blank.
4. Click on Start Discovery
NOTE: If this is the only domain, add a bogus domain (e.g. bogus_domain) since at least one domain has to be listed there, then delete the domain in question before adding it back.
