Verify app permissions
Under Authentication (Preview), select the Settings tab and check both boxes (Access tokens and ID tokens).
Under Certificates & Secrets, select Client secrets and create a new client secret and give it a unique and recognizable description. We recommend setting the expiration date to the maximum value.

Send Hadrius the details
We'll complete SSO setup from our side once you provide us with the Directory (tenant) ID, Application (client) ID, and the Client secret. These can be found on the Overview page.

The client secret is sensitive information. You can use flashpaper.hadrius.com to generate a one-time use secure link.
