(Optional) Advanced SAML properties The following advanced settings allow you to further increase security and debug the integration. Figure 1. Advanced settings Table 1. Advanced system properties table Property Description The number of seconds "notBefore" constraint, or after "notOnOrAfter" constraint, to consider still valid Enter the number of seconds to add to the NotBefore and NotOnOrAfter constraints to account for time differences between the IdP clock and SP clock. 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.
