A nice to have PowerShell Module when doing different kinds of PowerShell scripting against the FIMService in FIM 2010 R2 or MIM 2016. But just using the builtin FIMAutomation PSSnapin.

On codeplex and other places there are some great PowerShell libraries to use when scripting against FIM/MIM. But I often run into customers where third party dlls and addons are hard to get approved. So I started to make myself a small PS Module so that I didn’t have to rewrite the most common things all over. In the latest version of this I have also added pipeline support to some of the functions in it making it possible to for example make the following command.

GetByxPath -xPath "/Person[EmployeeType = 'Contractor']" | ImportObject | DeleteObject

This would delete all Contractors in the FIM Service.

Feel free to use it as is or cut functions into your own scripts when you need one.

<#
.SYNOPSIS
	PowerShell module containing functions to work with the FIMService in FIM 2010 R2 and/or MIM 2016.
	Accepts FIMService URL as Argument.
	Errorhandling within module is very limited. Calling script needs to handle errors.
.EXAMPLE
	Import-Module FIMServiceModule.psm1 -Argumentlist 'http://idmservice.konab.net:5725/ResourceManagementService'
.EXAMPLE
	Import-Module FIMServiceModule.psm1
	Will use default URI http://localhost:5725/ResourceManagementService
