<p class="MsoNormal">I was looking at the NativeSPSessions settings again wrt forceAuthn validation, and I was wondering:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The <code><span style="font-size:10.0pt">maxTimeSinceAuthn</span></code> setting on the SP claims to measure the authnInstant vs. “now”. Is there a reason the comparison isn’t vs. the “IssueInstant” on the assertion itself? Seems like that
might be a better way to check for a recent authentication, while leaving the overall timeskew adjustment work elsewhere. I can imagine cases where the timeskew on maxTimeSinceAuthn needs to be long enough to cause concerns with measuring “currentness”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have no idea whether there’s any real stats out there as to observed reasonable “maxTimeSinceAuthn” vs. “IssueInstant - AuthnInstant” values to use in a real deployment, but curious what people’s thoughts are.<o:p></o:p></p>
