Error "Unable to Authenticate User" and "Response issue time is either too old or with date in the future" Signing In with SAML

When you try to sign in to Tableau Server using SAML authentication, the following error might occur:

Authentication Failed
Unable to Authenticate User. Please try again or contact your Administrator for assistance.

In addition, the following message appears in the Tableau Server log files:

Response issue time is either too old or with date in the future...

Synchronize the system clocks on the computer running Tableau Server and the computer running the Identity Provider (IdP). For more information, see Synchronize the Time Server for the Domain Controller with an External Source on Microsoft TechNet.

The authentication response time from the IdP exceeds the allowed amount of time configured for Tableau Server.

By default, Tableau Server will accept authentication responses from your IdP that are within 2 hours of the authentication request.
