Most of our clients use laptops with Windows 7/8 installed on them. We just had the Aruba wireless AP's, Controllers and ClearPass installed last week and this week we're running into a problem where we have to uncheck "Validate Server Certificate" under properties for the connection for our clients to be able to connect. Doens't seem like a huge deal, except that anytime a clients machine restarts the check mark is there again and we have to go back down and uncheck it again. Times this by 50 teachers and come school time it's going to be a nightmare.
So my question is, do we need to install a certificate on our controller and backup controller, or is this a clientside problem? As of right now I know we do not have a server certificate installed on the controller.
Any advice is appreciated, I'm a Jr. Sys Admin and had this dropped in my lap, so feel free to explain it to me like I'm a five year old.
Thanks!
