We have implemented a wireless network for company employees that uses user based certificate authentication. It is working fine for laptops and iPhones, but we have been unable to get any of the android (Galaxy S4's) to work. We have installed the cert (both the root and user) on the phone. When we attempt to join, we get a setting box that has type, CA and user cert but also has a section named "IDENTITY". We set it to TLS, select the root cert for the CA section and the user cert (just called androiduser). But I have no idea what the "Identity" is. We have tried entering the user domain/ad_name, ad_name, etc. but nothing works.The whole reason behind the cert is so that users don't have to enter anything. I checked my wm3400 log and all it says is user authentication failed. Again, the same certificate setup works fine on laptops and iPhones/iPads. Has anyone had success setting up and android (specifically an S4 since each release of android changes something) on wireless with user certificates? If so can you let me know what steps you used.
