The purpose of using kerberos is to provide an additional layer of security to access cube data as well as provide insight into cube usage at a user level.

I have enabled Kerberos on both the Tableau server and delegation on the service account running MSAS on my analysis server. When i create tableau workbook using the MSAS data connection in desktop everything works fine and I can view my LDAP user accessing the cube using the SQL profiler.

The problem begins when I publish my workbook at data source to the Tableau server as I get the following error (keep in mind my data source is set to use "viewer credentials"):

Could not connect to server

An internal error occurred while establishing an impersonated database connection.
