CSCvv41414 - controller fails with an invalid PMKID

[jegan_rajappa]

Wireless client association fails during roaming.

when I upload RA trace in Cisco debug analyzer, it says 'controller could not validate PMKID for fast roaming'.

DNA center says 

'Invalid EAPOL(Extensible Authentication Protocol Over LANs) Key PMK(Pairwise Master Key)'

My 9800 controller is in 17.3.2a code, It looks like I am hitting this bug, but I am not seeing any work around.

I have already updated WiFi NIC drivers and still seeing same issues.

Does anyone experiencing the same issues?

I have exact the same issue, did someone find the solution? The clients are facing connectivities degradations becouse this issue.
Thanks

@Cristian_Sambido  If FT (802.11r) is enabled in your WLAN profile, then I would advise to disable the same and give a try, some clients have this trouble when authentication key management in WLAN profile is configured in mixed mode (802.1x and FT 802.1x).
