Problem Definition:

At the moment, the feature of Incremental Sync is only available for Active Directory only where JIRA would refer to the AD USNChanged attribute to check if the record has been updated. It appears OpenLDAP has a slapd module that will provide a 'usn' overlay to maintain the 'usnCreated' and 'usnChanged' operational attributes normally used by Microsoft ActiveDirectory.

Suggestion Solution:

It will be great for JIRA to implement Incremental Sync as well for OpenLDAP which it should also help the performance as it does not need to fully sync the entire directory every interval.
