<p class="MsoNormal">We are running Shibboleth IDP 2.3.8 at UCF on 4 Solaris servers in production (we are working on moving up to a more current IDP version). We are seeing a small but steady error rate in our Shibboleth idp-process logs on failed connections
to Microsoft Active Directory (Windows Server 2012 DCs). While the error rate is about 2/10 of one percent, I would prefer it to be zero. Does anyone else see patterns of these errors (see below) and what is an ‘acceptable’ error rate to other institutions?<o:p></o:p></p>
