Hello, I'm trying to retreive name of "authentication realm" like a variable in the Freeradius v3 ("LOCAL" in variable in my case). In debug log, near suffix module i see: (1) suffix: Checking for suffix after "@" (1) suffix: Looking up realm "yyyy.cz" for User-Name = "name@yyyy.cc" (1) suffix: Found realm "yyyy.cc" (1) suffix: Adding Stripped-User-Name = "name" (1) suffix: Adding Realm = "yyyy.cc" (1) suffix: Authentication realm is LOCAL I'm found in documentation, that the "Authentication realm" can be found in "control:Proxy-To-Realm" (https://networkradius.com/doc/3.0.10/raddb/mods-available/realm.html). At logs i have, but that variable is empty: (2) if ("%{control:Proxy-To-Realm}" != "LOCAL") { (2) ERROR: Failed retrieving values required to evaluate condition Thank you for the advice.
