I Change the user Group Value in NAC. After this no authentications are successfull. i Change back to the old configuration but also all Management Logins are rejected. I also reboot all NAC Gateways and Netsight Server but nothing helps. Does anybody have the same Problem or an idea.<BR /> <BR /> Thanks Nico<BR /> <BR /> Fri, 10 Nov 2017 17:01:00 GMT https://community.extremenetworks.com/t5/extremeswitching-vsp-fabric/management-login-to-switches-doesn-%CC%81t-work-anymore/m-p/8311#M1 Nico_Willamowsk 2017-11-10T17:01:00Z https://community.extremenetworks.com/t5/extremeswitching-vsp-fabric/management-login-to-switches-doesn-%CC%81t-work-anymore/m-p/8312#M2 I'm not sure what you've done exactly but have you enforced the changes to the NAC ?
