Inheritance of eap.conf settings

[Jonathan Gazeley]

Hi list,

I'm neatening up my sprawling FreeRADIUS config and I've noticed 
something strange.

Nothing uses the default eap.conf (and the default virtual server is 
disabled) but my understanding is that instantiations of the eap module, 
called like:

eap eduroameap {}

... should inherit settings from eap.conf. In my eap.conf I've set:

dh_file = /etc/raddb/certs/dh
random_file = /dev/urandom

And in my numerous EAP modules for various virtual servers, I've removed 
dh_file and random_file. Nothing complained about random_file being 
missing but apparently the dh_file being missing is an issue:

rlm_eap_tls: Unable to open DH file - (null)
rlm_eap: Failed to initialize type tls
/etc/raddb/modules/rainboweap[17]: Instantiation failed for module 
"rainboweap"
/etc/raddb/sites-enabled/rainbow-inner[17]: Failed to find "rainboweap" 
in the "modules" section.
/etc/raddb/sites-enabled/rainbow-inner[13]: Errors parsing authenticate 
section.

How come random_file was inherited while dh_file wasn't? Or have I 
misunderstood how this works, inerheritance doesn't exist, and it's just 
that random_file has a default value if undefined while dh_file doesn't?

Thanks,
Jonathan
