multiple-login checking

[Can Paçacı]

Hi,

Which method is better performance to limit for concurrent logins per 
user, Simultaneous-Use checking or checkrad?
Since simultaneus-use check performs "select count(*) .."  for each 
session in query.conf, it causes performance loss in db. Which method is 
suitable for the least performance loss?
Also, the NAS we use (Huawei-BNG) is not included in the NAS types list 
on the checkrad man-page.

The Freeradius version is 3.0.20.

Regards
