When you have more than 1 driver this makes it impossible to know which driver made what change and makes troubleshooting dependent on IDM driver trace files which causes performance issues.
Instead of the server name, the actual driver DN should be logged as the modifier/initiator for changes that the driver makes.
E.g. if the driver changes Given Name, then it should say so in the audit data, cn=my driver,cn=driverset,o=system instead of cn=myserver,o=system...
This would increase both security and usability and make troubleshooting much easier.
