Vote 2 for cloudpath, we have found the software to be extremely helpful in configuring, updating and troubleshooting clients.
As already stated this is expected behaviour. Like most IT Security "pains" the best approach is good communication & documentation to set user expectations and educate why it is important. One day it will feel normal like locking the doors of your house to protect assets. -- Jason Cook Technology Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Williams, Mr. Michael Sent: Wednesday, 17 April 2013 4:11 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Verifying or Validating Server Certificate when using WPA/WPA2 and 8021x WLAN Thanks Lee.

From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Lee H Badman Sent: Tuesday, April 16, 2013 8:38 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Verifying or Validating Server Certificate when using WPA/WPA2 and 8021x WLAN We found Cloudpath ExpressConnect to be wonderful at setting things like approved certs for the client- if you can get them to use it. We have a great mechanism with a "Help" SSID that allows for initial self-config, then self-remediation if you ever find your client not behaving. Works so sweet... except that new OS X and Win 7 machines also want to self-configure and onboard clients with just credentials needed (like for MS-CHAP v2/PEAP) and so our help tool gets unused. Expressconnect also lets you do things like disable IPv6, clear out "extra" profiles that accumulate, and other nice tweaks along with elegent cert handling. Lee H. Badman Network Architect/Wireless TME ITS, Syracuse University 315.443.3003 _____ From: The EDUCAUSE Wireless Issues Constituent Group Listserv [[email protected]] on behalf of Tim Cappalli [[email protected]] Sent: Tuesday, April 16, 2013 9:12 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Verifying or Validating Server Certificate when using WPA/WPA2 and 8021x WLAN This is definitely normal behavior. The only way to get around this would be to configure the client to not verify the server certificate which is a security risk and is not best practice. The idea is that if someone threw up a rogue AP with the same SSID and your users associated to it, they would receive a different certificate prompt which should throw a red flag (unforuntely it doesn't to college kids, they just click yes). tim Tim Cappalli, Network Engineer LTS | Brandeis University x67149 | (617) 701-7149 <mailto:[email protected]> [email protected] On Mon, Apr 15, 2013 at 11:34 AM, Williams, Mr. Michael <[email protected]> wrote: Our wireless network consists of a two Cisco wireless controller, 240 APs and we use Cisco ACS 5.2 as our RADIUS server. One of our wireless networks is configured to use WPA/WPA2 with 802.1x and PEAP w/ MSCHAP v2. After updating the server certificate on the ACS, our wireless users were asked to verify or validate the server certificate before gaining access to the wireless network. This requirement generates numerous helpdesk tickets and many more questions as to why the users must do this, when they don't have to do it on any other wireless network. I have asked Cisco for assistance but they informed me that what we are seeing is the normal behavior for the wireless supplicants and that the user must manually verify the authentication server certificate when a wireless profile is created for the first time or after the server certificate is changed on the ACS. I know we are not the only one seeing this requirements, numerous other University have publish wireless tutorials asking their user to verify the certificate as part of the initial setup of the wireless profile. I know we can eliminate this requirement in Windows machines by just unchecking the validate certificate option, but this is not an option on iOS machines. We use the 3rd party certificate by Incommon and have install both intermediate and root certificate on the ACS. Has anyone found a solution to this problem? Or is this just the default behavior of the supplicant that we are seeing? Thank you for your assistance. mike Michael M.
