  DHCP doesn't do VLAN tagging.  DHCP doesn't *know* about VLANs.

  I'm saying that if the user is in the wrong VLAN, then they're in the wrong subnet, and the DHCP server assigns them addresses from that subnet.

Is there a definite way to check if there are any VLANS assigned for the Authenticated users? I have access to the Radius server but do not have access to Homeserver. I hope the above makes sense. 

  Look a the RADIUS packets using wireshark.
