Viewer Credentials Option Unavailable When Publishing

Issue

When publishing a workbook or data connection from Tableau Desktop to Tableau Server with Kerberos enabled, Viewer Credentials option is not available as expected. Only 'Run As User' or 'Impersonate as Run As' user options are available.

Environment

Tableau Desktop
Tableau Server
MS SQL Server
MSAS
Kerberos

Resolution

After confirming that your environment has been successfully configured for Kerberos, complete the following steps:

Open Tableau Desktop and select 'Help > Settings and Performance > Clear Saved Server Sign-ins'. This will clear all old connection information from Tableau Desktop.
Run the following command from a command prompt run as Administrator on the computer running Tableau Desktop:
klist purge
The above command will clear Kerberos user tickets off of the system.
Launch Internet Explorer in Private mode, and navigate to the Tableau Server URL. This step prevents any active sessions or cookies from being brought back in during the Kerberos authentication process.
Launch Tableau Desktop and sign into Tableau Server.
Open a new connection to the data source.
Publish this data connection or workbook to Tableau Server, and confirm that 'Viewer Credentials' is now an Authentication option.

Cause

This behavior is related to a known issue which is currently under investigation.

Additional Information

Before attempting resolution, confirm that the Tableau Server environment and database have been successfully configured for Kerberos.
