Dynamically assign a computer in a VLAN

[Mathieu RINCK <mathieu.rinck () laposte net>]

Hi everyone,

We want to assign dynamically a Workstation or Laptop in a "trusted"  
VLAN, after authentication based on username, password and mac address.
I know we can assign a computer to a VLAN with its mac address with 
VMPS. Can RADIUS or TACACS do the same, added with username/password 
authentication ?

Thanks all for your answers.
