Azure AD SAML with OIDC Client Protocol for Grafana SLO(Single Logout) having problems

Hey everyone,

I’m not sure if this is even possible.

But right now we have Azure AD as an external SAML-based IdP which we use to authenticate users.
We use mappers and other claims to get attributes from SAML requests through Keycloak and finally to our end application (Grafana).

Login work nicely, with me getting redirected to Azure Login page and finally receiving all claims I need on Grafana.

However when I try to logout, I do get a page from Azure saying

You signed out of your account
It’s a good idea to close all browser windows.

I assume it should successfully log me out, but when I hit the grafana home page, it redirects me to grafana dashboards, without asking me for authentication.

This issue does not occur if I close my browser after logout.

Grafana logs tell me i’m successfully signing in and out from grafana.

But keycloak logs give me the following stuff
