Mapp works great. (We are running 8.2.1) Powershell 3.0 or higher required.
Will this work in a SaaS Cherwell environment?
David, yes it can work hosted. The runbooks (One-Steps) are executed from the full client so as long as your IT have rights to run AD commands you can use it. If you want to run with an Automation Process, you have to move that Server into your environment and disable it in SaaS.
