Possible causes

If Digipass Authentication for Remote Desktop Web Access does not perform any processing (i.e. the module does not produce any trace output), ensure it has been registered for the website it is designated for.

Solution

During installation, the module is registered with the modules of IIS. This registration should be inherited from all installed websites. Ensure that inheritance is enabled, or explicitly register the IIS-native module for the relevant website(s).

To ensure Digipass Authentication for Remote Desktop Web Access is registered in IIS

  1. Open Internet Information Services (IIS) Manager and select the appropriate server.

  2. Select Modules.

  3. Verify that Digipass Authentication for Remote Desktop Web Access is in the Modules list.

If Digipass Authentication for Remote Desktop Web Access is not included in the Modules list, register it in IIS.

To register Digipass Authentication for Remote Desktop Web Access in IIS

  1. In the Actions panel, select Configure Native Modules.

    The Configure Native Modules dialog is displayed.

  2. Click Register.

    The Register Native Modules dialog is displayed.

  3. Type Digipass Authentication for Remote Desktop Web Access into the Name field, browse to %PROGRAMFILES%\OneSpan\Digipass Authentication for Remote Desktop Web Access\DIGIPASSPlugin_IIS_RemoteDesktop.dll, and click OK.

  4. In the Configure Native Modules dialog, select Digipass Authentication for Remote Desktop Web Access and click OK.

    Digipass Authentication for Remote Desktop Web Access appears in the Modules list.

Alternatively, to prevent performance issues, you can register Digipass Authentication for Remote Desktop Web Access for a specific website.
