I am in the processes of changing out a Meru controller based system for Aruba Instant IAP 205's. I have a Windows 2012 R2 domain controller authenticating clients through RADIUS using computer authentication. All client machines are Windows 7 SP1.
Everything seems to work fine except domain resources that require authentication. I have total internet access and I can ping all the domain machines using hostnames. I can even ping domain.local and I get replies from the domain controller, but when I try to access a network share I get a password prompt saying "cannot contact a domain controller to service the authentication request." I also cannot run gpupdate /force because it fails to find a domain controller.
The domain controller is also DHCP and DNS, which are working fine. I have narrowed it down to an Aruba issue because the Meru access points at the other end of the building are using the same RADIUS server and the same VLAN as the arubas, but the meru clients have no issues at all. Everything also works on the wire. I just can't seem to get the arubas to allow domain activity.
I found this similar problem posted a couple times in the Airheads community, but no difinitive solution has been presented on those threads.
