I have implemented a solution based on Novell/NetIQs Identity Manager's SOAP driver. There is a driver health job too and a driver health configuration on my SOAP driver.
There is a query query-driver-ident at driver startup and regulary when the driver is running. The question is: why is the query answered by the system when the driver starts and why is it passed through when the driver is running? When the query is passed through: what is the connected system expected to reply?
Details follow:
When the driver starts I see the following trace which is quite ok:
[12/11/13 13:13:18.558]:Codex-KMS ST:Received state change event.
[12/11/13 13:13:18.559]:Codex-KMS ST:Transitioned from state '%+C%14CStopped%-C' to state '%+C%14CStarting%-C'.

However, when the driver is running and the driver health job checks the trace is as follows:

The error UNSPECIFIED_ERROR is generated by my application on the web service end point which is not prepared for this query.
The answer to Your first question, IMHO, is 'cause there is driver shim written so to answer ident query only first time after start.
There is at least two ways You can use to overcome this error: 1. Configure driver health job (located under Driver Set) to not use "subscriber heartbeat". This setting affects all drivers. 2. Veto such query in sub-ctp: if (operation="query" and @event-id="query-driver-ident") then veto();
