How to set Global Property Authenticate Preemptively through maven POM

Every test steps has Pre-emptive auth property set to 'Use Global Preference'.

I tried to set global property Authenticate Preemptively through maven POM given below : 

<configuration>
<projectFile></projectFile>
<globalProperties>
<globalProperty>preemptive=true</globalProperty>
</globalProperties>
</configuration>

However this is not working. SOAPUI is sending first request without any credentials and second request with credentials.

I think that property name that is used in above POM is incorrect..

Does anyone know what exactly is the property name for Authenticating preemptively ..

Any feedback is highly appreciated.
