Certificate push for eap-tls clients

  Thanks for the messages back. I'd forgotten about insertion of the CA
into the certificate chain with openssl, which is helpful. I guess it
would be useful to experiment with using a certificate tool, web server
and autogenerated html page via php or something to give the user a
one-time link if they are put into the "remuneration" vlan by
freeradius. No idea how you start packaging up profiles but maybe the
CAT tool is useful there. Seems to always be a case of "use the
commercial or brew your own" with what I'm doing at the moment!

As you say you're AD based, just in case you didn't realise: if your
clients are all Windows and joined to the domain, then CA management is
automatic and they will have a client cert on them that you can just use
to authenticate, so the domain manages that side for you and you don't
need to worry about it.

Of course, if some clients aren't domain joined then you do still have
the cert deployment issue, which is the usual issue with EAP-TLS. As
Alan said, you probably want to look at some other deployment system.
FreeRADIUS isn't that.

Remember you can still make an intermediate signing cert with e.g.
OpenSSL, sign it with the domain CA, then use that to generate all certs
for non-domain members, if you don't/can't use the AD cert services
