We are currently running 9 HiveAP141 (all HiveOS 6.5r5) with HMOL Enterprise 6.8r4. One AP is set as Radius Server for authenticating users against our Domain Controller. For months the problem persists, that if the DC is rebootet, our users can't login into the WLAN anymore. I can solve this, if I go to Configuration -> Advanced Configuration -> Authentication -> AAA User Directory Settings and Join it again. Then a 'Validate User' to verify it and upload the configuration to our Radius Server AP. Then everything is allright again.
I searched this forum, but the only post i found was to check the ntp & clock Settings, which are in sync in my configuration. Any thoughts, because it's getting tiresome (after every Windows Update the mentioned workaround above)...?
