  Ah.... then it's rather more difficult to fix.

  That error message from OpenSSL is all we have/

  Well... no.  I don't rewrite documentation for vendors.

  We have documentation on how to configure EAP-TLS.  See mods-available/eap.  It's relatively straightforward.

  If the error is in OpenSSL, then you have to figure out *what* to configure.

  The server works by default.  There is no magical setting which turns off a *broken* configuration and enables a *working* one.
