We also tried "EAPOL-rate-opt". It did help with the Mac roaming issue, but it adds too much overhead and affects throughput quite a bit. We are on 6.3.1.1, and I still see the issue (testing on Macbook running Mavericks). Only fix that worked (per user fix) for us, is unchecking OCSP and CRL under keychain/preferences/certificates.

It's a new setting in 6.1 and while it didn't help in my testing, I've heard others have had success with it. Would someone care to update with details? We have had issues with MacOS devices and roaming. Three "variables" were suggested - OKC, PMKID, and EAPOL-rate-opt. We had OKC / PMKID both enabled, no EAPOL-rate-opt, and "interval between ID requests" at 30 seconds. Wandering around a well-covered building with a MacOS laptop pinging a fixed target and it would disassociate / reassociate / reauthenticate with significant delay in between; Windows laptop did not have this issue (maybe drop a packet or two between roaming targets). We tried disabling OKC by itself, but it seemed to make no difference. This was discussed on the list before so I'll not repeat the whole issue. We tried the EAPOL-rate-opt, and we would drop a handful of pings, but essentially keep a connection intact. So yes, it did appear to help. It's not 100% still (is anything wireless ever 100%?) but was a solid improvement over the previous case. We're still "grabbing at straws" to improve the mobility, and hoping perhaps the "sticky client" voodoo in 6.3 might help the issue as well.
