Taken into account that I've never tested SAKE/AKA/SIM/PAX as phase 2
methods, I would not claim any support for them in the current
implementation.

Yes, it sounds like the configuration for SAKE and PAX may be incorrect.
They have worked fine in my tests when used as the main EAP method.

I would assume you are using hostapd as a RADIUS server. It will first
try to start the EAP method you have configured as the first entry for
the provided user identity. If the supplicant refuses (EAP-Nak) that
method, it will ask for another one and hostapd will accept the other
method if it was enabled in the eap_user configuration file.

It will accept them if the client asks for them and they are enabled in
user configuration.

Which settings? Identities and passwords are set in the hostapd.eap_user
file.

hostapd will use methods that are enabled for the user (based on the
identity) in hostapd.eap_user.
