i want redefine DEFAULT set of Simultaneous-use

DEFAULT NAS-Port-Type == Virtual, Simultaneous-Use := 1 Fall-Through = 1

that for all users, but for someone need "Simultaneous-Use := 2" if add "Simultaneous-Use := 2" to specific user entry, this not work.

i found for gnu radius manual:

= Additivity = Replace ^(*)

Hm, why do you read a user manual for product A and expect it to work with product B? Reading "man 5 users" might be a better approach, it tells you interesting things about the Fall-Through attribute. The solution is to add another entry for your special user before the DEFAULT one, which does not reach the DEFAULT entry, i.e. yourusername NAS-Port-Type == Virtual, Simultaneous-Use := 2 DEFAULT NAS-Port-Type == Virtual, Simultaneous-Use := 1 Fall-Through = 1 (note the absence of Fall-Through to make processing stop after the match) Greetings, Stefan Winter -- Stefan WINTER Stiftung RESTENA - Réseau Téléinformatique de l'Education Nationale et de la Recherche Ingenieur Forschung & Entwicklung 6, rue Richard Coudenhove-Kalergi L-1359 Luxembourg E-Mail: stefan.winter@restena.lu     Tel.:    +352 424409-1 http://www.restena.lu               Fax:      +352 422473
