What I would do. Use the etc_group module Create som groups for your users Group1 Group2 Add the respective users to the correct groups In the users file I will create a line for each login server (client to the raidus server) Something like this: Client-IP-Address == [login server1], Radius-Group == ”[name of group]” Take a look at the module etc_group to see how you create a group. Then remember to add the group etc_group name to the authentication section of your radius site probably the sites-enabled/default Best regards Jan Madsen Fra: freeradius-users-bounces+jmd=kmd.dk@lists.freeradius.org [mailto:freeradius-users-bounces+jmd=kmd.dk@lists.freeradius.org] På vegne af Spacelee Sendt: 22. juli 2010 12:34 Til: FreeRadius users mailing list Emne: How to separate users to different server...
