Thanks! I understood the logic, but I tought there was an integrated way to do so. I think I will simply call a python script to do the verification.
There is. You can use unlang[1] to do some of this, as well as using the xlat engine, i.e. "%{sql:SELECT username from ...}"[2] [1] http://freeradius.org/radiusd/man/unlang.html [2] https://wiki.freeradius.org/modules/Rlm_sql Do note though that the actual account linking to the MAC address probably should *not* be done in FreeRADIUS...
