Need to change bulk users Samaccountname to uppercase
Hello I am trying to get this script to update a list of samaccountname from lowercase to uppercase. We have an application that has issues with lowercase. I have tried the below and it is giving me a "You cannot call a method on a null-valued expression" error when running. I am not sure what I am doing wrong but any help will be greatly appreciated. Here is the script I am using now.
$users = get-content '.\users.txt'
foreach($user in $users){
set-aduser $user -SamAccountName $user.samaccountname.toupper()
}- Here's a working example:
$users = Import-Csv .\users.csv
$users | % { Set-ADUser $_.SamAccountName -SamAccountName $_.SamAccountName.ToLower() }
- For that to work, you need to use a CSV file with a column SamAccountName to designate the user (and Import-CSV instead of Get-Content).
- Thanks for the reply Vasil. When creating the .csv file and adding the column. Running the script now gives me the below error.
set-aduser : Object reference not set to an instance of an object
At C:\Scripts\Domain MIgration\TEST.ps1:3 char:1
+ set-aduser $user -SamAccountName $user.samaccountname.toupper()- Here's a working example:
$users = Import-Csv .\users.csv
$users | % { Set-ADUser $_.SamAccountName -SamAccountName $_.SamAccountName.ToLower() }
