The hotfix repairs a compatibility issue between MS PEAP and "third party radius servers" (i.e. ACS).</P><P></P><P>I could successfully login in and out of the XP machine without any network outage since the client is configured to use machine credentials when user credentials are unavailable. Unfortunately, I had a problem with reauthentication, which caused network connectivity to fail after resuming from standby or hibernation.</P><P></P><P>The patch fixed the problem and added another. Following network login/logout, I lose network connectivity for 60 seconds (configurable via dot1x timeout quiet-period).</P><P></P><P>Anyone know what is going on and if there is a hotfix to fix the hotfix?</P> Sun, 04 Jul 2021 19:16:16 GMT https://community.cisco.com/t5/wireless/peap-authentication-failure-with-acs/m-p/601498#M20444 mspiegelman 2021-07-04T19:16:16Z Re: PEAP authentication failure with ACS https://community.cisco.com/t5/wireless/peap-authentication-failure-with-acs/m-p/601499#M20445 <HTML><HEAD></HEAD><BODY><P>Hi</P><P></P><P>Im about to deploy PEAP and I found also the same problem.
