ADAL: Where do I view the resource ID's? - azure

Question

I'm new to using adal-node npm package.
In the example it mentions:
var resource = '00000002-0000-0000-c000-000000000000';
Where is this ID from? From my use-case, I just want to batch update users in my AD.

Answer 1

A resource is a service/app/api for which you ask an Identity provider like Azure AD to issue tokens for. You can also you the AppId (client Id) as a resource as well
'00000002-0000-0000-c000-000000000000' is the client Id of Azure AD Graph API (https://graph.windows.net/ ). This Api is being deprecated in favor of Microsoft Graph "https://graph.microsoft.com", which is the resource you should use.

Answer 2

The value of the resource is a URI that identifies the resource for which the token is valid.
If you want to use Microsoft Graph API to update your users in your AD, you should use https://graph.microsoft.com for the resource.
You can refer to this sample. You will get the graph client to update the users.
const AuthenticationContext = require('adal-node').AuthenticationContext;
const MicrosoftGraph = require("#microsoft/microsoft-graph-client");
const authorityHostUrl = 'https://login.windows.net';
const tenantName = ''; //azure active directory tenant name. ie: name.onmicrosoft.com
const authorityUrl = authorityHostUrl + '/' + tenantName;
const applicationId = ''; //application id for registered app
const clientSecret = ''; //azure active directory registered app secret
const resource = "https://graph.microsoft.com"; //URI of resource where token is valid
const context = new AuthenticationContext(authorityUrl);
context.acquireTokenWithClientCredentials(
resource,
applicationId,
clientSecret,
function(err, tokenResponse) {
if (err) {
console.log('well that didn\'t work: ' + err.stack);
} else {
let client = MicrosoftGraph.Client.init({
defaultVersion: 'v1.0',
authProvider: (done) => {
done(null, tokenResponse.accessToken);
},
});
client
.api('/users')
.get((err, result) => {
console.log(result, err);
});
}
});
