Prepare Users for First ACS Login
ACS namespace creation has been restricted, and Access Control Service will be retired soon. For more information, see https://aka.ms/accesscontrolservice.
After you have completed all of the steps needed to use Access Control service (ACS) to authenticate users, you can set up new users to use ACS, or you can modify existing users to use ACS. You must send the User Name and Authentication Key values to the users and instruct them to submit these values when they log on to a Dynamics NAV client, either Microsoft Dynamics NAV Windows client or Microsoft Dynamics NAV Web client.
For more information, see How to: Create Microsoft Dynamics NAV Users.
When users first access the Microsoft Dynamics NAV Windows client or Microsoft Dynamics NAV Web client, they are asked to log on. When they sign in, they must provide the user name and authentication key that you sent them. The user name and authentication key are validated by the one of the identity providers that you specified in the Microsoft Azure management portal. If the user is already signed in, or if the user has previously chosen the Keep me signed in field in the browser, the sign-in page does not appear.
When a user has been authenticated by the ACS identity provider, the user's ACS identity is tied to the Dynamics NAV user. The next time the user logs on, Dynamics NAV will not request the authentication key because the user account is recognized as a Dynamics NAV user.
When the Administrator opens the User page and edits the User card for a user who has successfully logged on using ACS authentication, the ACS Access Status value will change to
