At first I tried validate PMKID with OKC on; but then also tried OKC off. Neither had any noticeable affect. Research brought me to what was the sw-retry setting; no Temporal Diversity. You don't think it won't have any benefit to 802.1x authentications timing out?
I've had very inconsistent experience, mostly from MacBooks and to some degree to iPads. I originally thought it to be ClearPass Policy Manager issue, but seemed to have ruled that out with TAC, they wanted to involve the controller team, but I have not gotten to that yet (next step). I've gone thorugh all the recommendations for Macs that I know of and from this community, but still having the problems. I am trying to determine if indeed it is Aruba or Apple related. It's a K-12 with very little Windows; which don't seem to have any issues.
Thanks
