[midPoint] importing resource

[Ashwill, Steven L]

Hello,
I tried using the sample task below but it seems to start over every time it is stopped or has an error. Is there something I'm doing wrong? Is it possible to make it pick up where it left off if it has an error. Or is it possible to filter out any records that already have a shadow? We have about 1.5 million records so preferable I would like to be able to filter it down to users that have reset their password in the last 2 years.  This is about 300,000.  
<task>
    <name>Import: Example Resource</name>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionState>runnable</executionState>
    <activity>
        <work>
            <import>
                <resourceObjects>
                    <resourceRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2"/>
                    <objectclass>ri:inetOrgPerson</objectclass>
                </resourceObjects>
            </import>
        </work>
    </activity>
</task>




Thanks,

Steve
