I'm using the following module for radius authentication.

https://github.com/qudreams/nginx-http-radius-module

Is this module is too old to use ?

Thank you,


Did you read my email earlier in the thread? You can get it to work (I got
it to work) but the client lib it uses is dated and it needs okay
dictionary files ,
