The WLAN controller polls the RADIUS server for a complete list of authenticated users and groups after each user authentication.

The RADIUS server sends a group name return list attribute to the WLAN controller during every successful user authentication. 

The RADIUS server forwards the request for a group attribute to an LDAP database service, and LDAP sends the group attribute to the WLAN controller. 

The RADIUS server sends the list of authenticated users and groups to the WLAN controller as part of a 4-Way Handshake prior to user authentication.

Sharing cached keys between controllers during inter-controller roaming created vulnerabilities that exposed the keys to attackers. 

Because OKC is not defined by any standards or certification body, client support was delayed and sporadic early on. 

Key exchanges during fast roams required processor-intensive cryptography, which was prohibitive for legacy devices supporting only TKIP.

The Wi-Fi Alliance continually delayed the creation of a client certification for OKC, even though it was defined by IEEE 802.11r.
