Sheriff is very rigorous in locking the licence to its hosting machine. Some locking mechanism include Machine ID, Machine Signature, Disk Signature and File Signature. Some developers wish to relax some locks under certain circumstances. The API function SLS_SetSessionOptions can be called to temporarily bypass some locks within a session.

Disk Signature is the signature of the hard disks.

Machine Signature is the signature of other hardware components including include CPU, BIOS, Motherboard etc.

Machine ID = Machine Signature + Disk Signature + Signature of OS
