The time synchronization between Tableau Server and the SAML identity provider Ensuring time synchronization between Tableau Server and the SAML identity provider is a common and crucial aspect to check when troubleshooting SAML authentication issues. SAML assertions often have time constraints, and discrepancies in system times can lead to failed authentications. Option A is incorrect because network bandwidth and latency, while important for overall performance, are less likely to be the cause of SAML-specific issues. Option C is incorrect as storage capacity of the Tableau Server is generally not related to handling SAML authentication re-quests. Option D is incorrect because version compatibility of the web browser, while important for user experience, is not a common cause of SAML authentication problems.
