Poll mode has some interesting quirks.

The documentation suggest that polling can generate a delta from the
previous poll but I can't find this functionality anywhere in the
driver.

The driver parameter "Search Results to Synchronize on First Startup"
appears to be absent. Is this just me or is the documentation plain
wrong.

Also. Polling generates a "full-modify" with every attribute returned
plus those specified in the driver filter, I don't understand why it
doesn't generate an add instead.
