When the BIG-IP system is configured as a SAML Service Provider (SP), APD can crash if the IdP connector object that is used specifies a single logout URL. A crash occurs only when the SP receives a SAML assertion that does not include a SessionIndex attribute in the AuthnStatement element.
APD crashes, SAML authentication fails.
1. IdP sends Assertion without SessionIndex element in AuthnStatement. 2. IdP connector on BIG-IP has single-logout-url specified (not empty).
To work around the problem: 1. Reconfigure IdP to send Assertion with SessionIndex attribute in AuthnStatement element, or 2. Clear single-logout-url in IdP connector object on the BIG-IP system.
