Manage Shadow Group Membership - PowerShell Function I looked at a quick script to update a shadow group here , and then thought, this would make a good function. I have used my function template (refer to that post if you want to know more about how to format a function), to build up a reusable script to update group membership based on user and computer object location in AD. A traditional shadow group is all members of an OU. In my mind, there are a few assumptions to this statement. Being that you have taken the time to create an OU, put objects in it, and created a group to mirror those objects, you probably have only 1 type of object (i.e. user) and they are all similar in some respect (i.e. same office location). This function takes that in mind and only updates groups with users or computers - not other groups etc. Moving away from the traditional meaning of shadow group, I have added (for my own benefit as I required the functionality) a parameter to change the searchsco...

Manage Shadow Group Membership with powershell AD Cmdlets Sometimes, in our Active Directory structure, we need a group to reflect the contents of an OU. One example of this is If you organise you users and computers in location specific OU's and need to use RODC password replication policy. In this script I use PowerShell v2 AD cmdlets to enumerate group membership and OU membership and then use compare-object to work out the differences. Finally the switch reads if the additional user was found in the group or the OU and either adds or removed the member accordingly.

I am wouking on a more comprehensive solution using get-adobject to deal with multiple object types. $Group = "shadowgroup" $OU = "OU=ShadowOU,DC=domain,DC=com" $users = $(get-aduser -SearchBase $OU -filter "*") $groupmembers = Get-ADGroupMember -Identity $Group switch (Compare-Object -ReferenceObject $gro...
