HOWTO WLAN Access Point authenticate user via kerberos

[John Mok]

Hi,

I am new to FreeRADIUS. I would like to set up FreeRADIUS, such that 
access point authenticates WLAN users via Kerberos (or GSSAPI / 
Kerberos) and grant access to the wired network upon successful 
authentication.

Is FreeRADIUS the right tool to use? If so, I hope someone could point 
to the documentation how to set it up. Is there any requirement on the 
access point, e.g. support for 802.1X is sufficient?

Thanks a lot.
