We are having an issue logging into wireless. If I am authenticate at one location on campus I have no problems authenticating there at any time. However, if going to a different part of campus, different ap, I can not authenticate and the attempted authentication does not even show up in the passed or failed attempts log on the acs server. I can see the WiFi and I am able to obtain an IP. So, dhcp is working properly. I just can't authenticate.
All of our ap's are the light weight 1010, controlled by a 4402 controller. Authentication goes through the ACS controller which queries the LDAP server. It doesn't appear to be an LDAP issue because I don't have authentication problem as long as I authenticate to the same ap every time.
The default group they belong to allows an unlimited number of authentications.
