1. Configure Microsoft Entra SSO - to enable your users to use this feature.
   1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
   2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
2. Configure Blink SSO - to configure the Single Sign-On settings on application side.
   1. Create Blink test user - to have a counterpart of B.Simon in Blink that's linked to the Microsoft Entra representation of user.
