HI,

Use this script:

var gr = new GlideRecord('u_ad_group_lookup');
gr.addQuery('u_user_ad_domain',adDomain);
gr.addQuery('u_application',application);
gr.query();

if(gr.next()){

var str = {};
str.adGroup = gr.getValue('u_ad_group'); //first value I need to pass back
str.adDomain =gr.getValue('u_group_ad_domain'); //second value I need to pass back

var data = json.stringify(str);
gs.info('returned data is '+data);
return data;

Thanks,
Ashutosh
