if the authority url is something like https://login.microsoftonline.com/domainName (where the domain name is a domain associated with your tenant) I get the following error
Get Token request returned http error: 400 and server response:error description AADSTS90002 Tenant 'organizations' not found This may happen if there are no active subscriptions for the tenant. Check to make sure you have the correct tenant ID
the code works fine in case the authority_url is something like https://login.microsoftonline.com/{Guid} (where the Guid is the tenant ID)
sample code:
var authorityUrl = 'https://login.microsoftonline.com/organizations';
var authContext = new AuthenticationContext(authorityUrl, undefined, undefined, '');
var token = await this.authContext.acquireTokenWithClientCredentials(this.resourceId, this.clientId, this.clientSecret);
Using "adal-node": "0.2.1"
The error message states that the tenant you have specified ("organizations") does not exist. Try providing a valid tenant name instead.
I.e. https://login.microsoftonline.com/YourOrgName.onmicrosoft.com where "YourOrgName.onmicrosoft.com" should be replaced with your tenant name.
