How to do SAML authentication in SOAP UI

Hi,

In  our application, we are using ODATA services to interact with the SAP HANA DB (There is no intermediate channel like java in between UI and backend). For authentication, we are using site minder. Site Minder will send a SAML tokken to HANA, which will inturn verify the user.

So, If have to automate ODATA services, I need to give authentication (username and password). But I cant use basic authentication in SOAPUI for my application as it uses SAML token. 

Is there anyway where I can do SAML authentication in SOPAUI?

I saw something about WS security configurations, but did not understand about keystore or signature stuff.

Please help me with this issue.

Thanks,

J
