These constraints prevent against replay attacks by denying requests that are not made within the specified time frame. If the IdP clock and SP clock are significantly different, network latency may result in the SAML request being unauthorized. This property adds a grace period during which SAML requests and responses are still considered valid.| |Turn on debug logging for SAML 2.0 Authentication|Select **Yes** to enable additional logging information for SAML 2.0 events.|
