Upgrade seemed to go fine. Today I come in to find out that no one is getting authenticated. I have APs in WLSE configed with WDS that are not authenticating. I also have AP's not in WLSE that are not authenticating. All these worked before the upgrade. </P><P></P><P>Any ideas??</P><P></P><P>Thanks,</P><P>Becky </P> Sun, 10 Mar 2019 22:42:31 GMT https://community.cisco.com/t5/network-access-control/acs-authentication-errors/m-p/1029951#M407488 mccullrrcisco 2019-03-10T22:42:31Z Re: ACS Authentication Errors https://community.cisco.com/t5/network-access-control/acs-authentication-errors/m-p/1029952#M407489 <HTML><HEAD></HEAD><BODY><P>Are you getting any messages in the logs on the APs or in the ACS server?</P></BODY></HTML> Tue, 11 Mar 2008 14:46:01 GMT https://community.cisco.com/t5/network-access-control/acs-authentication-errors/m-p/1029952#M407489 artegall1 2008-03-11T14:46:01Z Re: ACS Authentication Errors https://community.cisco.com/t5/network-access-control/acs-authentication-errors/m-p/1029953#M407490 <HTML><HEAD></HEAD><BODY><P>Yes.
