If you do not change the expiration period, Connection Server will stop accepting SAML assertions from the SAML authenticator, such as a Unified Access Gateway appliance or a third-party identity provider, after 24 hours, and the metadata exchange must be repeated.
Use this procedure to specify the number of days that can elapse before Connection Server stops accepting SAML assertions from the identity provider. This number is used when the current expiration period ends. For example, if the current expiration period is 1 day and you specify 90 days, after 1 day elapses, Connection Server generates metadata with an expiration period of 90 days.
