We are a Cloudpath customer. It is not going to help you prevent Apple issues with certificate changes. It will install all the necessary certificate chains, as well as provision all client settings. We use EAP-TLS, and it has made the distribution of certificates a trivial matter. Most important for network engineers that are using EAP methods that pass username and password is the ability to CORRECTLY configure systems to reduce their vulnerability to man in the middle attacks. Of course, this doesn't prevent a client from manually incorrectly configuring their wireless profile.
There are really smart shops, like UVA, that designed their own onboarding software, but for those that want a quick turnkey option, Cloudpath will work.

I am interested to know how products like CloudPath XpressConnect can make this process seamless to users. If any XpressConnect customers can elaborate on this, that will be great!

I think if I were in your shoes, I would pick a few client mac addresses in the logs, and look at their sessions and make sure they are connected now. I will be you'll see them connected just fine. In any event, when we do a certificate change on our authentication servers, we issue campus wide change notices as a result of some of the aggravation.

In our setup, only the root & intermediate certificates are configured on the client. We can then update our server certificates without any issue as long as we continue to use the same certificate chain.

Our ACS server is configured to send all intermediate CAs to clients together (so the client can chain the certificate all the way to its trusted root authority) with the server certificate and we are renewing the certificate with the same CN name and same trust chain. I talked with our certificate provider Thawte and they said it is Apple's issue. Could you let me know how the CloudPath XpressConnect Wizard can avoid this issue? --- Dennis Xu Analyst 3, Network Infrastructure Computing and Communications Services(CCS) University of Guelph 519-824-4120 Ext 56217 d...@uoguelph.ca www.uoguelph.ca/ccs ----- Original Message ----- From: "Bruce W Osborne (Network Services)" <bosbo...@liberty.edu> To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Sent: Friday, October 11, 2013 7:48:23 AM Subject: Re: [WIRELESS-LAN] Wireless authentication issue after certificate renew We use CloudPath XpressConnect Wizard to provision our clients.

The certificate is used for wireless PEAP authentication. After the renewal, we noticed some 5411 EAP timeout errors in ACS logs and the error mainly happened for Apple devices. When we checked it on one Iphone, it could not automatically connect to the wireless network (it used to connect automatically). Then we had to manually connect to the network again and acknowledge certificate on Iphone then it can connect. Android and Blackberry devices do not have this issue. I am thinking what we can do to make the certificate renewal process seamless. Has anyone experienced this issue as well and do you have any solutions? Thanks in advance. --- Dennis Xu Analyst 3, Network Infrastructure Computing and Communications Services(CCS) University of Guelph 519-824-4120 Ext 56217 d...@uoguelph.ca www.uoguelph.ca/ccs ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
