You can troubleshoot the driver by using the DSTrace utility. You should configure the utility’s options by selecting Edit > Properties > Identity Manager Drivers.
For each event or operation received, the driver returns an XML document containing a status report. If the operation or event is not successful, the status report also contains a reason and a text message describing the error condition. If the result is fatal, the driver shuts down.
After you have configured the DSTrace utility, you can monitor your system for errors.
