Configuring Microsoft Dynamics NAV Web Client by Modifying the Web.config File
To install the Microsoft Dynamics NAV Web client, you run Microsoft Dynamics NAV 2015 Setup. Setup installs a website with a web server instance for the Microsoft Dynamics NAV Web client on an Internet Information Services (IIS) server and configures the connection from the Microsoft Dynamics NAV Web client to Microsoft Dynamics NAV Server. After the installation, you can use Microsoft Dynamics NAV 2015 Administration Shell to add additional web server instances for the Microsoft Dynamics NAV Web client. The connection information is saved in the web.config file of the web server instance. After installation, you can change the configuration by modifying the web.config file.
About the Web.config File
The web.config file is an .xml file that you can edit with a text editor, such as Notepad.
Locating the web.config file
You can have multiple Microsoft Dynamics NAV web server instances on IIS. Each instance has its own web.config file that is stored in the physical path of the application's virtual directory. The path is %systemroot%\inetpub\wwwroot\[VirtualDirectoryName]. For example, the folder for the default Microsoft Dynamics NAV Web client instance is %systemroot%\inetpub\wwwroot\DynamicsNAV80 folder.
Note
After you modify the web.config file, if you have Microsoft Dynamics NAV Web client open in the Internet browser, the changes will not take effect until you close the browser session, and then reopen Microsoft Dynamics NAV Web client.

Specifies the TCP port for the Microsoft Dynamics NAV Server. This is part of the Microsoft Dynamics NAV Server’s URL. Values: 1-65535 Default value: 7046 |
ServicePrincipalNameRequired |
If this parameter is set to true, then the Microsoft Dynamics NAV Web client can only connect to a Microsoft Dynamics NAV Server instance that has been associated with a service principal name (SPN). If this parameter is set to false, then the Microsoft Dynamics NAV Web client attempts to connect to the configured Microsoft Dynamics NAV Server service, regardless of whether that service is associated with an SPN. For more information about SPNs, see How to: Configure Delegation for Microsoft Dynamics NAV Web Client. Default: false |
SessionTimeout |
Specifies the maximum time that a connection between the Microsoft Dynamics NAV Web client and the Microsoft Dynamics NAV Server can remain idle before the session is stopped. In the Microsoft Dynamics NAV Web client, this setting determines how long an open Microsoft Dynamics NAV page or report can remain inactive before it closes. For example, when the SessionTimeout is set to 20 minutes, if a user does not take any action on a page within 20 minutes, then the page closes and it is replaced with the following message: The page has expired and the content cannot be displayed. The time span has the format [dd.]hh:mm:ss[.ff]:
Default value: 00:20:00 |
ShowPageSearch |

The Search for Page or Report option only finds objects that are available from the Departments page in the Microsoft Dynamics NAV Windows client.
If you do not want to the Search for Page or Report icon available in the Microsoft Dynamics NAV Web client, then set the parameter to false. Default value: true |
UnknownSpnHint |
Specifies whether to use a server principal name when establishing the connection between the Microsoft Dynamics NAV Web client server and Microsoft Dynamics NAV Server. This setting is used to authenticate the Microsoft Dynamics NAV Server, and it prevents the Microsoft Dynamics NAV Web client server from restarting when it connects to Microsoft Dynamics NAV Server for the first time. You set values that are based on the value of the ServicePrincipalNameRequired key. Value: The value has the following format. (net.tcp://NavServer:Port/ServerInstance/Service)=NoSpn|SPN
Default value: (net.tcp://localhost:7046/DynamicsNAV80/Service)=NoSpn If you set this key to the incorrect value, then during startup, the Microsoft Dynamics NAV Web client will automatically determine a correct value. This will cause the Microsoft Dynamics NAV Web client to restart. Note
For most installations, you do not have to change this value. Unlike the Microsoft Dynamics NAV Windows client, this setting is not updated automatically. If you want to change the default value, then you must change it manually.
|
DnsIdentity |
Specifies the subject name or common name of the service certificate for Microsoft Dynamics NAV Server. This parameter is only relevant when the ClientServicesCredentialType is set to UserName, NavUserPassword, or AccessControlService, which requires that security certificates are used on the Microsoft Dynamics NAV Web client and Microsoft Dynamics NAV Server to protect communication. Note
You can find the subject name by opening the certificate in the Certificates snap-in for Microsoft Management Console (MMC) on the computer that is running Microsoft Dynamics NAV Web client or Microsoft Dynamics NAV Server.
For more information, see How to: Set Up User Authentication for the Microsoft Dynamic NAV Web Client. Value: The subject name of the certificate. Default value: none |
ACSUri |
This parameter is only relevant if the ClientServicesCredentialType parameter is set to AccessControlService. With the AccessControlService setting, users are authenticated by using either Microsoft Azure Access Control service (ACS) or Microsoft Azure Active Directory (Azure AD). The value of this setting depends on whether ACS or Azure AD is used to authenticate users. When using ACS authentication, the ACSUri parameter specifies the URI of the ACS login page for relying party applications. An example of a URI is https://CRONUSInternationalLtd.accesscontrol.windows.net/v2/wsfederation?wa=wsignin1.0%26wtrealm=https%3a%2f%2flocalhost%2f. For more information, see How to: Configure the Microsoft Dynamics NAV Web Client for ACS. When using Azure AD authentication, the ACSUri specifies the URI of the authentication page for the Azure AD tenant where users sign in. An example of a URI is https://login.windows.net/[Tenant_ID]/wsfed?wa=wsignin1.0%26wtrealm=https%3a%2f%2flocalhost%2f. [Tenant_ID] specifies the Azure AD tenant. When the Microsoft Dynamics NAV application has external access and multiple Azure AD tenants are required, you can replace [Tenant_ID] with common. For more information, see Authenticating Users with Azure Active Directory. Optionally, you can specify a wreply query parameter. The wreply query parameter tells the Azure AD authentication service where to send the authentication token, and the parameter must point to the SignIn.aspx page of the Microsoft Dynamics NAV Web client. If you do not specify the wreply parameter, it will be deducted from the URL in the browser. The value of the wreply parameter must correspond to a Reply-To address in the Azure AD application pointed out by the wtrealm query parameter value. Important
The query string parameter must be URI-encoded. This means, for example, use "%26" instead of "&".
Default value: none |
HelpServer |
Specifies the name of the Microsoft Dynamics NAV Help Server that the Microsoft Dynamics NAV Web client must connect to, such as MyServer. Default value: none |
HelpServerPort |
Specifies the TCP port on the specified Microsoft Dynamics NAV Help Server that the Microsoft Dynamics NAV Web client can access Help through, such as 49000. Default value: none |
