Multiple VLAN value per user

Hi, Most of dynamic VLAN assignment implementations use these RADIUS attributes to work: Considering a user from VLAN 100: Tunnel-Type = 13, #VLAN Tunnel-Medium-Type = 6, #IEEE-802 Tunnel-Private-Group-Id = "100" Is there a way for freeradius to return multiple values in Tunnel-Private-Group-Id. I'm working in a project where I want a user to belong to multiple vlans. At the moment, working with a sql database. I'll appreciate your help, thanks in advance. Best regards, Germán Espinoza
