I have some project to deploy Extreme NAC server and the client is authenticated via LDAP Blind using account proxy (no use administrator). I have configured AAA config on NAC for Ldap and tested users (via wired) on Nac successfully. And then, tested user (via wireless) on EWC it seems error state description "Rejected by radius mschap". I have tested both oh windows 8 and windows 10 PC's. Is this error caused by using a proxy (not use administrator) account on LDAP?
