Issue/Introduction

Does IDP initiated SAML require session store when the SP is SiteMinder and the IDP is using ADFS with HTTP POST Binding?

Environment

Release : ALL

Component : SITEMINDER - FEDERATION

Resolution

No, this configuration does not require the session store, however, some optional features of this use case, such as Single Log Out (SLO) require the session store (SLO requires persistent sessions, which require the session store).
