You can do this by following this procedure:
Note: This procedure may temporarily interrupt AuthAnvil authentications. If the server is protected by a Windows Logon Agent or Credential Provider, make sure that you have the override password handy so that you can regain access to the machine.
- As a safety precaution, back up the AuthAnvil database using the instructions in the Backing Up the AuthAnvil Database section of the AuthAnvil Installation Guide.
- Create a new AADBuser account on the local machine.
- In SQL Management studio, assign the new local user identical permissions as the existing domain user. NOTE: You will also want to assign a local administrative user sysadmin permissions to the server so that you can still manage SQL after the server is no longer domain joined.
- Run AAWebConfigEditor.exe, located by default in C:\Program Files\Scorpion Software\AuthAnvil\AuthAnvil Tools\AAWebConfigEditor.exe. Tab through the controls until "Apply" is highlighted, then press Ctrl + O. This will enable editing of the impersonation fields. Set the username, password and domain to the correct values. (Domain should be set to the computer name).
- Click "Apply".
- Disconnect the computer from the domain.
- Ensure that DNS is resolving properly, and that you can reach the SAS URL specified in AAWebConfigEditor.exe from the server itself.
- Test an authentication against the AuthAnvil Manager (http(s)://servername/AnvilManager).
