Ok. Apologies but not in front of a computer right now.

I have been working on a script for the last week to process a csv where some people exist already in AD and some don't.

The script all works fine. New users are created with all fields including the name field in AD OU to show :

Firstname Lastname IDNumber

This is also their display name such as:

Bob Jones [0001743]

ID number is their login name and pulled from. Csv

The issue is existing users

It does everything including displayname as above, but doesn't update what AD shows as "Name" when viewing the OU. I'd imagine this is the CN and have been messing with rename-adobject but I need it to do this as part of processing one user at a time, so ideally at the end of the line where I am doing all of my set-aduser variables.

This is cosmetic really but if I can fix that bit, I can stop thinking about it

Thanks in advance
