PowerShell : How do I fix displayName attribute for all users in Active Directory ?
For small shops that do not leverage automated provisioning tools, they face challenge in keeping the attributes for Users and other objects in AD standardized. For similar situation, recently I was asked from Access Control team if there is an easy way to fix the displayName attribute for all users or to fill in the display name where its missing based on the Users’ first and last name. The answer is a simple PowerShell one-liner using Quest Cmdlets.
Using Get-QADUser cmdlet, you can define the location of all your users using the –searchlevel parameter or you can sweep the whole directory for all user accounts. And then pipe the results to the foreach and use Set-QADuser to fix the display names (in this example) based on the users’ first and last name
Get-QADUser mydomain.int/users -sl 0 | foreach {Set-QADUser $_ -DisplayName ("{0} {1}" -f $_.firstname,$_.lastname)}
The –sl 0 parameter defines the limit of users to 0.
