Issue

When attempting to login to Tableau Server after configuring Kerberos, the following error might occur: 
"Tableau Server could not authenticate you automatically. Sign in using your Tableau Server credentials."​

Additionally, an error similar to the following can be found in the httpd error.log:
 "gss_display_name() failed: A required input parameter could not be read: An invalid name was supplied (, Unknown error), referer: <URL of Tableau Server>" 

Environment

  • Tableau Server
  • Kerberos

Resolution

Update "gateway.public.host" value to ensure it matches the case returned from the DNS. If the DNS returns all lowercase, ensure that "gateway.public.host" is all lowercase. 

Cause

Certain values in regards to Kerberos are case sensitive. If the "gateway.public.host" does not exactly match DNS and what's configured in the .keytab, etc, Kerberos Authentication will fail.
