Date Mar 22, 2023
Checkmk Edition Checkmk Enterprise (CEE)

Level Trivial Change
Class New Feature
Compatibility Compatible - no manual interaction needed

Checkmk required both the response and the assertion statement to be signed in order to accept an authentication request response from the identity provider. However, as per the SAML specifications, only the assertion statement signature is required and the response signature is optional. For this reason, authentication request responses that only have the assertion statement signed are now accepted.
