Moving license server

[yzamecfw]

We are currently trying to transition our license for FumeFX with MR support from an artist's workstation to the render cluster. We have an auth code that works for manual authorization on a workstation but the same code does not work on the cluster master; I assume because the User ID does not match what we were given.

Is the User ID actually auto-generated per-machine? Do we need a new auth code to make this work on the license server?
