KB484146: "Your credentials or authentication mode is incorrect” error message appears when attempting to log in to the MicroStrategy for Tableau connector

Description

When using Tableau Public or Tableau Desktop versions 2019.4 or later, if Strategy Library’s cookies are configured to sameSite=none, you will receive an error message when trying to log in using the Tableau connector that says: “You credentials or authentication mode is incorrect.”

Why is this happening? 

Tableau Public and Tableau Desktop use an embedded browser to display the Tableau Connector. Starting from version 2019.4, the embedded browser, QTWebEngine 5.10, is based on Chrome V61, which rejects the sameSite=none cookie flag. For details, click here.

Solution

To avoid the error message, proceed with one of the following workarounds: 
 

Workaround 1

1. Install an Apache Server and configure it to proxy the Strategy Library Tomcat web server.
2. In the

   https.conf

   file, enable the mod_header module. 
3. Add the following between the markers

   <IfModule headers_modules> ... </IfModule>

   :
   

   Header edit* Set-Cookie "(.*)(; SameSite=None)" $1;	"expr=%{HTTP_USER_AGENT}=~ m#Chrome\/ [5-6][1-6]#i"

   
   
4. Save the file and restart the Apache Server.

Workaround 2

1. Deploy a separate instance of Strategy Library on your web server. This instance should not be configured for the sameSite flag.
2. Use this instance when importing data from Tableau.
