In response to our blog post on bulk updating Active Directory User Attributes a user out there asked us via support whether the same was possible to do with Active Directory Group Attributes. Indeed, you can use the power of powershell bulk update group functions.
Indeed, the same principles can be used to update groups. Look at using Get-ADGroup (https://technet.microsoft.com/en-us/library/ee617196.aspx) and Set-ADGroup (https://technet.microsoft.com/en-us/library/ee617199.aspx) for the technique to change from bulk updating users to bulk updating groups.
Web Active Directory’s PeopleNexus product allows you to bulk provision, de-provision, and update users and groups from your data sources without scripting by allowing you to use a configurable administrative user interface. You can perform these updates ad-hoc from the user interface or hands free using provided processes and REST services that can be scheduled to run with whatever frequency you want.
