Hello
We have deployed intregration with various PMS, including Micros Fidelio and SIHOT, but we are using our own software solution that's able to comunicate with any RADIUS (this includes ClearPass). The problem with this kind of integration it's Micros will charge you around 6K € for every interface they show to you, and you have to provide a lot of information and even a agreement for code development.
So our solution it's based on a middleware using CHAR interface, this allow us to skip this process and even support Micros Specials.
Short answer (hope a Aruba rep deathourize me) right now there is no "plug and play" solution for ClearPass Micros integration.
Sorry for the answer.
