This script synchronizes the client descriptions from OPSI to the AD.

  - You will have to store a mysql.exe binary in the same directory as the script. 
  - Replace >DATABASE-HOST< >DATABASEUSER< >PASSWORD< >DATABASE< (near mysql.exe) and >YOUR-DOMAIN-SUFFIX< (near ForEach) to fit for your setup
  - Make sure your MySQL server listens ( bind-address in my.cnf ) 
  - Execute this script as Domain-Administrator on an DC



This Script requires Powershell 3
