Hi All, I've got my setup working so that the outer auth is dealt with by EAPTTLS and then the inner is dealt with by either PAP/MD5 depending on what device the client is using (Windows doesn't seem to support MD5 and Apple doesn't seem to support PAP without extra config). My question is regarding the /mods-available/inner-eap module. My setup seems to be working but finding out that this module exists has made me question that fact. Instead of configuring inner tunnel within the /mods-enabled/eap file (e.g. setting the virtual server to your inner tunnel server and then configuring the inner tunnel virtual server in /sites-enabled/inner-tunnel etc.) do you HAVE to use /mods-available/inner-eap for this kind of setup to work correctly? When reading the documents I wasn't sure if the inner-eap module was going to be more heavily relied upon in v4.0.0 (I'm on v3.2.1) but wasn't necessary at the moment? Kind regards, Connor
