When PingFederate sends an artifact to your IdP's SSO or SLO service endpoint, an element in the message indicates how long it should be considered valid. On the Artifact Lifetime screen, specify the expiry information in seconds.
You can change the default value per your requirements, if needed. Also consider synchronizing clocks between your server and your partner's SAML gateway server. If clocks are not synchronized, you might need to set the artifact lifetime to a higher value.
This step applies only to SAML 2.0 connections.
Override the default value of the Artifact Lifetime field.
The default value is 60 (seconds).
If you are editing an existing connection, you can update the artifact lifetime.
