Value of -1 Returned When Requesting Trusted Ticket Using Single Sign On with Proxy

Issue

When configuring Tableau Server for single sign on, a value of -1 might be returned when requesting a trusted ticket, even though the correct IP address is added to the list of trusted hosts. Additionally, the httpd log files show that the requesting IP address has a port number included at the end of the IP address.

Environment

  • Tableau Server
  • External load balancer or proxy

Resolution

Review the proxy or load balancer settings and disable any option to include TCP port form client IP address.

Cause

External load balancer or proxy server is configured to forward the TCP port from the client IP when requesting the trusted ticket.
