Is your server certificate signed by one of the common CAs (i.e.,
something that is included in trusted CA lists) or is this an in-house
self-signed CA (if yes, how is the CA certificate distributed to

wpa_supplicant can be configured to trust a set of CA certificates,
e.g., using a single PEM file with multiple files or using ca_path
parameter to point to a directory of trusted CA certificates. For
example, ca_path="/etc/ssl/certs" would do this on a Gentoo system (that

and altsubject_match parameters can be used to configure requirements
for the authentication server certificate, e.g.,
