Using SET-QADUser to change CN attribute

Hi,

I need to update a bunch of users names to title case (John Smith). Currently everything is upper case.

Set-QADUser -Identity "john.smith" -DisplayName "John Smith" -ObjectAttributes @{cn="John Smith"}

Using the command above, the displayName corrects to title case, but cn won't change. It doesn't even show in the change log.

I feel like I am missing something obvious.

I also checked to see if I had any other policies that may be switching cn back to all upper case, but there are none.

Any ideas on what I might be missing? I can change it manually in the ARS console so I know it is possible.

Side note, I thought about using a policy in ARS to change the case, but I need to do a bunch of checking before actually applying the change, so I would prefer to do it through an external script.

Cheers
