Alternative Powershell GUI for basic management of Active Directory accounts.
A little hacky, and probably has bugs, but also pretty simple compared to other options. Probably won't work straight out of the box, but shouldn't need too much tweaking.
Needs a recent-ish version of Powershell (4.0 works for me):
PS C:\Users\Administrator> $PSVersionTable.PSVersion
Major Minor Build Revision
----- ----- ----- --------
4 0 -1 -1
Take a look at the script - there are a set of global variables that will probably need tweaking to your environment.
Run it with Powershell, under a user account that has necessary privileges for account administration actions.
Please don't ask me to write Powershell for you.
