Web Config Changes:
 adding this line to  <appSettings> section:
 
 <add key="SCROMDomainUrl" value="moodle web application url" />
       <add key="ASUserId" value="moodle site administrator userid"/>
       <add key="ASPassword" value="moodle site administrator password"/>

Where needed, add the control itself:
