In the Spotfire.Dxp.Web.Log error:

=====================================
ERROR 2016-03-08 07:19:52,539 [nxow0vwe0dkpkuscm0sjsxfr, 2960, 50, NBKVSMJ] Spotfire.Dxp.Web.Forms.Error - ClientError: Unable to open analysis '/myFolder/MyReport'.
System.InvalidOperationException: Adapter authentication mode configuration is missing in web.config.
=====================================

This will normally be seen with the following data connectors.

For each data connector to work with TIBCO Spotfire Web Player, the corresponding data adapter settings must be present in that Web Player instance's web.config file. The adapter settings for the following data connectors are not present in the web.config file by default, and must be added manually.

              Kerberos        To connect using Kerberos authentication.
              Prompt          To prompt the user for credentials.

For example, if you are adding an OData adapter, you will need to add the following within the <adapters> node:

<adapter name="Spotfire.ODataAdapter" mode="Prompt"/>

Steps:

1). Edit the web.config in a plain text editor (like Notepad).

2). Update the adapter settings as described above and per the manual.

3). Save the web.config file.

4). Restart IIS or the TIBCO Spotfire Web Player application pool.

Note: In Spotfire versions 7.5 and higher, all data connectors are present by default in the configuration file.

Installation and Configuration Manual.

• Chapter: 6.4 Data from External Sources
• Excerpt: TIBCO Spotfire can access data directly from several external data sources using the Spotfire Data Connectors. To be able to use analyses with data from these sources in Spotfire Web Player, you must specify the authentication method in the web.config file for how users will connect to the external data sources.
