Configuring multiple, chained EAP methods (i.e. EAP-TTLS-EAP-MD5-EAP-TNC)

Hi, is it possible to configure multiple eap methods that must all be executed for a user? I.e., I am thinking of something like: - establish a TTLS tunnel - do EAP-MD5 for user authentication - do EAP-TNC for platform authentication Currently, I just managed to do either EAP-MD5 or EAP-TNC inside the TTLS tunnel, not both. I see no option in the config files where multiple eap methods can be added. Thanks, Ingo
