EX4200 Port Security

I currently have an EX4200 with the enabled ports locked down to the MAC or MACs of the workstations on them with the "allowed-mac and mac-limit". I know have users with laptops wanting to move around offices and connect to ports other than theirs. How would I allow this with port security? Am I better off removing the individual port security, opening all ports and allowing all my known MACs on the entire switch? If so how would I accomplish this or if there is a better way, wht is that?

Thanks!
