Hi,

I have an authorization module to write for FreeRADIUS that does a fair amount of CPU intensive SQL queries 1-2 seconds time. But the problem is that when a 802.1x authentication is occuring this event occurs many times 4-5 times at each reception of RADIUS Access Request. Also, at that time the username is not the final one (normally the final one is sent within the MSCHAPv2 from within the TLS tunnel used by PEAP or EAP-TLS or EAP-TTLS).

Is there a way for my authorization module to trigger the work to be done only if EAP is at the stage of handling the internal authentication? Can for example my module communicate with the EAP module and look at an internal flag somewhere to know if the TLS tunnel has been completed?

I would like the following:

Access Request (EAP identity response) -> authorization module - no CPU intensive

<-- Access Challenge (EAP TLS Server Hello)

Access Request (EAP TLS Client Hello) -> authorization module - no CPU intensive
<-- Access Challenge

etc. until TLS is established

Access Request (EAP TLS MSCHAPv2) -> authorization module - CPU intensive query
<-- Access Accept
