HI,

I want to Authenticate service management rest api using the Active Directory. Can you please mention the Steps?

I have tried to authenticate using node.js module as follows it shows as the authorization error. Please let me know anything i have missed in the following

var adal=require('adal-node');
var AuthenticationContext= adal.AuthenticationContext;
var tenantID="57d091d4-4dae-41e2-9a2b-0bc0644688df";
var clientID="fd6bec69-7e92-49a0-85b1-affb20a9d7af";
var resource="https://management.azure.com/";
var authURL="https://login.windows.net/" + tenantID;
var secret="E7ZaMHCNqcO4qHzzJm6RI4X7kS7CTVUjNJ/13eCltvI=";
var context=new AuthenticationContext(authURL);

var rest=require('restler');

context.acquireTokenWithClientCredentials(resource,clientID, secret, function(err,tokenResponse) {

console.log('err:'+err);
console.log('tokenResponse:'+JSON.stringify(tokenResponse,null,2));

authHeader = tokenResponse['accessToken'];
requestURL="https://management.azure.com/subscriptions/84da9df4-cf54-4040-9743-9fbbda1903f0?api-version=2015-01-01";
rest.get(requestURL, {accessToken:authHeader}).on('complete',function(result)
{
    console.log('result:'+JSON.stringify(result,null,2));

});
});
