Not comparable as completely different product, but i use OIDC in a Proxmox Cluster and it has one set of ClientID / Secret which is distributed over all nodes, and on the IDP all redirect-uri’s ( per node) have been entered there, so whichever node does a request it will always receive information back to a/the correct redirect-uri.
Now for CMK, there is not yet ‘builtin’ support so it can not be configured/managed from within CMK (compared to SAML).
Plus SAML is only available on the CEE edition, whereas i use the RAW edition.
So to get around it i use an OIDC apache module to facilitate this.
