Hello list, I'm trying to enable "Simultaneous-Use := 1" for all our users. Currently, usernames and passwords are in the radcheck table and authentication works without issues. The DB also contains the DHCP ip pool. I did the following: 1. Enabled "sql" in session in sites-available/default 2. Uncommented "simul_count_query" query in mods-config/sql/main/mysql/queries.conf And from https://github.com/FreeRADIUS/freeradius-server/blob/master/doc/configuratio... I get: INSERT INTO radgroupcheck (GroupName, Attribute, op, Value) values("dialup", "Simultaneous-Use", ":=", "1"); Does that mean I have to assign all my users to a group ('dialup') or can I use Simultaneous-Use somewhere else so that the default for all users is 1 for instance?
