Configuring Microsoft Dynamics NAV Server

  • Artículo

When you run Microsoft Dynamics NAV 2015 Setup and install Microsoft Dynamics NAV Server, you can provide configuration information that is then used as the configuration for the default Microsoft Dynamics NAV Server instance.

After you install Microsoft Dynamics NAV Server, you can change any of the settings that you provided during Setup, or any of the Microsoft Dynamics NAV Server settings, using either the Microsoft Dynamics NAV Server Administration tool or the Microsoft Dynamics NAV Windows PowerShell cmdlets for Microsoft Dynamics NAV 2015.

Note

Each Microsoft Dynamics NAV Server instance has its own settings.

Configuring Microsoft Dynamics NAV Server in Setup

You can configure the default instance of Microsoft Dynamics NAV Server when running Microsoft Dynamics NAV 2015 Setup. You must first select Microsoft Dynamics NAV Server as a component to install. To do this, select one of the following Installation Options that includes Microsoft Dynamics NAV Server:

You can also customize your installation and the list of components to install. For more information, see How to: Choose Components to Install.

After you specify an installation option or customize your component list, the Specify parameters pane is displayed in Setup. The list of parameters that you see in the Specify parameters pane depends on which components you have selected for configuration. Setup provides a short description for each parameter. For a description of the most important parameters for Microsoft Dynamics NAV Server, see Server Option.

When you have finished entering values, choose the Apply button. This returns you to the Specify parameters page in Setup.

After you finish running Setup, you can modify Microsoft Dynamics NAV Server using any of the methods described in the following section.

Configuring Microsoft Dynamics NAV Server After Installation

After you install Microsoft Dynamics NAV Server, you can change any of the settings that you provided during Setup, or any of the Microsoft Dynamics NAV Server settings, in any of the following ways:

  • Using the Microsoft Dynamics NAV Server Administration tool. For more information, see Settings in the Microsoft Dynamics NAV Administration Console and The Microsoft Dynamics NAV Server Administration Tool.

  • Using the Microsoft Dynamics NAV PowerShell cmdlets that are available in the Microsoft Dynamics NAV 2015 Administration Shell. For more information, see Using Microsoft Dynamics NAV Administration Shell Cmdlets to Modify Settings.

  • By directly editing CustomSettings.config, the Microsoft Dynamics NAV Server configuration file. By default, this file is located in C:\Program Files\Microsoft Dynamics NAV\80\Service\Instances\<instancename>. We recommend that you do not directly edit the configuration file, because if you make any errors in typing, then you may not be able to start the instance.

Important

After you modify a Microsoft Dynamics NAV Server setting, you must restart the associated Microsoft Dynamics NAV Server instance before any changes can take effect.

Settings in the Microsoft Dynamics NAV Administration Console

In the tables in the following sections, Microsoft Dynamics NAV Server Administration tool setting names are used. Settings names in the CustomSettings.config file are slightly different. Quotation marks are required for all values.

  • General Tab Settings

  • Client Services Tab Settings

  • SOAP Services Tab Settings

  • OData Services Tab Settings

  • NAS Services Tab Settings

  • Management Services Tab Settings

Note

You must choose Edit in the Microsoft Dynamics NAV Server Administration tool before you can modify any values.

General Tab Settings

The following table describes fields on the General tab in the Microsoft Dynamics NAV Server Administration tool.

Setting Description

Azure Active Directory App ID URI

Specifies the App ID URI that is registered for Microsoft Dynamics NAV in the Microsoft Azure Active Directory (Azure AD). You use this setting to configure Microsoft Dynamics NAV web services for OAuth authentication, specifically when the Credential Type setting is AccessControlService.

The App ID URI is a logical identifier and does not have to represent a valid location, although it is common practice to use the physical URL of the Microsoft Dynamics NAV web service.

The App ID URI is typically the same as the value of wtrealm parameter of the ACSUri setting that is included in web.config file for the Microsoft Dynamics NAV Web client and the ClientUserSettings.config file for the Microsoft Dynamics NAV Windows client.

An example of an App ID URI is https://localhost:7047/.

For more information about how to use the Azure Active Directory App ID URI with OAuth authentication, see Using OAuth to Authenticate Microsoft Dynamics NAV Web Services (Odata and SOAP).

Build Restriction

Specifies what happens when a Microsoft Dynamics NAV client tries to connect to the Microsoft Dynamics NAV Server instance when the client is running a different build version of Microsoft Dynamics NAV 2015 than the server instance.

Values:

  • AlwaysConnect

    The client connects to the server instance without giving a warning to the user.

  • WarnClient

    Before connecting the client to the server instance, a message appears that informs the user that the build versions for the client and server instance are different. The user can choose to continue or cancel the connection.

  • DoNotAllow

    A message appears that informs the user that the client and server instance build versions are different, and the client does not connect to the server instance.

Default: WarnClient
