If you deploy the Microsoft Dynamics NAV Web client in a multitenant deployment architecture, URLs that must access a specific tenant must specify the tenant ID. However, the Microsoft Dynamics NAV Web client can be accessed from URLs that specify a host name. If your deployment must support host names for tenants, then you must enable the corresponding URL rewrite rule in the web.config file for the Microsoft Dynamics NAV Web Server components.
To enable the URL rewrite rule to configure the Microsoft Dynamics NAV Web client to accept host names for tenants
On the computer that is running the Microsoft Dynamics NAV Web Server components, open the web.config file that is located in the physical path of the web application for the Microsoft Dynamics NAV Web client.
The path is %systemroot%\inetpub\wwwroot\[VirtualDirectoryName]\WebClient. For example, the folder for the default Microsoft Dynamics NAV Web client application is %systemroot%\inetpub\wwwroot\DynamicsNAV90\WebClient.
Note You must open the web.config file as an administrator or have permission to modify the file.
<system.webServer>element, find the
<rule name="Hostname (without port) to tenant" enabled="false" stopProcessing="true">element, and then change the value of the
enabledattribute to true.
Save and close the web.config file.
This enables support for host names for the Microsoft Dynamics NAV Web Server components. If a tenant has been mounted with a host name as an alternative ID, the Microsoft Dynamics NAV Web client will accept a URL that contains this host name to identify the tenant.
If you create a non-tenant specific app for SharePoint that accesses the Microsoft Dynamics NAV Web client by using Microsoft Azure Active Directory, the resulting URL includes a parameter that specified a SharePoint host URL. This represents the URL for opening the Microsoft Dynamics NAV Web client that you have specified in the app manifest. You must enable a URL rewrite rule in order to accept the URL.
