IssueWhen Tableau Server has been configured for SAML authentication, users intermittently receive the following error:
Unable to Sign In
Invalid username or password
The VizPortal logs, when set to log at the debug level*, indicate the following:
...DEBUG org.springframework.security.saml.websso.WebSSOProfileConsumerImpl - Validation of received assertion failed, assertion will be skipped
org.springframework.security.authentication.CredentialsExpiredException: Authentication statement is too old to be used.
*The Tableau Server VizPortal logs must be set to debug level before the error is encountered in order to log the error message shown above. For more information about logging levels, refer to Change Logging Levels
