Redirect after timeout logout

[danielstieber]

Hey, I intend to logout users via SLO when the session is timed out. I'm testing with OneLogin, but need to work with other providers as well.

I log the user out via redirecting to route saml.logout when the session is over. That basically works, so far so good.
But the redirect always brings me to the normal SSO Login and then to the OneLogin Dashboard.

I actually want the user to be logged out via SLO and then being redirected to /saml2/xxx/login ., so when he logs back in, he is back in the app, maybe even with a redirectTo to his last position.

I've tried filling the relay state url in the DB. If I use the smal2/xx/login url, then I'm in an endless loop. If I fill out any other url, then I'm getting there and am logged back in without ever being logged out at IdP(?)

Any ideas?
