I've configures NAC as an external captive portal in EWC. When the client connects, it gets the Unregistered policy. After registration, the NAC changes the clients policy to Guest Access, but the EWC remains the Unregistered. I need to disassociate the client form the EWC to set the EWC the Guest Access profile. The NAC and the EWC are synchronized to the same NTP server and are in the same VLAN. Does somebody have any idea how to resolve this issue?
