Is checkmk SAML 2.0 capable?

Strange thing noticed since i switshed my (originally CentOS7) LXC container where i run CMK in to CentOS8, and afterwards to RocklyLinux 8,5.

The SAML implementation keeps functioning ok, however if i setup a new box and use the same modules it borks.
the issue seems to underlying due to Lasso, i just cannot understand that in the upgrade it did not break the CMK box, but all new ones break.
The issue revolves around : https://dev.entrouvert.org/issues/25640

details :

  • mod_auth_mellon-0.14.0-12.el8.x86_64
  • mod_auth_mellon-diagnostics-0.14.0-12.el8.x86_64
  • lasso-2.6.0-12.el8.x86_64

As both 2.6.1 and 2.7.0 have been released as versions of Lasso , somewhere 2.6.1 is not available for either CentOS8 (yes i know support has ended) or RocklyLinux 8.5
CentOS7 still functions with Lasso 2.5.1, however downgrading is not an option, next to the fact that CentOS7 does not run anymore on latest ProxMox due to not (correctly) supporting CGroupv2​ functionality.

So please do beware if this issue i have encountered ( untill a higher version of Lasso is available)
