SimplSAMLphp, when used as a proxy, does not properly propagate SLO requests from upstream Identity Providers. Received on it's SP endpoint they will simply terminate the SP session.
So in a given setup:
A SLO Request from a Our SP will be propagated to the Their SPs, but a SLO Request from a Their SP will not be propagated to the Our SPs.
