The problem here is simple. The juniper can forward all dhcp requests to 
a separate DHCP server, but how can I make the dhcp server see witch 
unit/vlan the request is comming for to distribute the correct ip 
address to the client?

Does anyone knows if the Juniper M series supports option 82 to tell 
witch vlan/unit the request is coming from?
