Hi,
I have recently updated Tableau Server to 2018.1 from 10.5.3. Since that, Trusted Autentication is not working properly. I am able to get a ticket and use it in an url to get the dashboard but when I what to interact (for example clicking on a pie) I get this message:
An error occurred communicating with the server (500).
This may be a temporary network condition. Please retry the operation.
If this condition persists, contact your system administrator.
Outside trusted authentication, dashboards works fine.
Anyone facing the same situation?
Thanks in advance.
Regards.
Tableau does not recommend using unrestricted trusted tickets. Unfortunately the best option is to roll back to 10.5 until Tableau can release a fix for 2018.1. Instructions on rolling back: Rolling Back to an Earlier Installation of Tableau Server | Tableau Software
The reason we do not recommend unrestricted trusted tickets:
1. Trusted tickets only allow access to views and not to the Tableau Server UI. This means that redemption of a ticket doesn't allow any TS UI/vizportal functionailty, just using views.
2. Unrestricted trusted tickets give full access to the server as the user the ticket was requested as.
3. If someone was to gain access to the machine requesting trusted tickets they could request a trusted ticket as the administrator, redeem it, and have full access as an administrator to the server. This is one of the reasons trusted tickets only allow specific IPs and not ranges of IPs for adding to trusted hosts to request tickets.
4. This full session is good for the length of time that wgserver.session.idle_limit / wgserver.session.lifetime_limit are to (default no more than 240 minutes of inactive use).
If you believe that you have secured your environment enough that #3 is not a concern, unrestricted tickets is a workaround. However, you are choosing to open the door to your server much wider than it otherwise would be.
