Radius scripts are broken for NAS which don't give their IP
In the radius script (freeradius_utils/auth.py:256 and radius/api/views.py:66), we consider the case where a NAS doesn't send its ip address but only its domain (see freeradius_utils/auth.py:135). Since Django 2, this query doesn't work anymore, because the validator validate that nas_id
is a valid ipv4 address before the first query is done.
