Chris,
sorry that bothering you again, two days tried to implement different solutions. First of all, LDAP doesnt work, authentication works (same like Radius), but still nothing in logs (except Windows machines, even if they are not part of domain, i see them and usernames). Your solution, i tried to implement it but, still dont understand how it should works. WLC, i configured an accounting server is CheckPoint, on checkpoint side i configured WLC like Radius Client, i think its wrong. I guess, in my configuration, i have Windows NPS, and turned on Radius accounting there , and WLC and CHeckpoint have to use it like Radius server, no? CHeckpoint support advised to use Captive portal for access to wireless ... but i am not sure... in this case i have to provide open access to wireless corp, and next check users, then they will try to get access to network via checkpoint policy...
