users is configured correctly in the web.config file of the
Microsoft Dynamics NAV Web client and on Microsoft Dynamics NAV
Server.
- The correct authentication method is enabled
on the Microsoft Dynamics NAV Web client site in IIS.
- For Windows authentication, the correct
authentication providers are configured on the Microsoft Dynamics
NAV Web client site in IIS.
