Recently we upgraded all our internal CA servers to use SHA256 and renewed the root certs accordingly. When we changed the radius server to use the new root CA it breaks our 802.1X wireless network on campus. Opneed a case with Aruba and they put it back to the old SHA1 and it is working now but we to use SHA256 - anyone else make this change and what am I missing?

It depends on the client, but many clients will simply refuse to connect when the server's certificate changes regardless. Did you test it with any of your clients?

Yesterday, I swapped to SHA256 on radius server and when Idisconnect wifi on iphone and reconnected it failed. The only way Aruba could get it to work was swapping back to SHA1 cert. I even forget wireless network and still nothing.
