I am trying to write a script for user creation. I would like to set the user logon name (pre-windows 2000) while I'm running the script and entering thee user information.

Answer 1

You just need as include the -sAMAccountName attribute. So

New-ADUser `
-Name $displayName `
-GivenName $firstName `
-Surname $lastName `
-DisplayName $displayName `
-sAMAccountName $samaccountname `
-UserPrincipalName $pName `
-AccountPassword(ConvertTo-SecureString $password -AsPlainText -Force) `
-PasswordNeverExpires $True `
-Description $description `
-EmailAddress $email `
-Path $path `
-Enabled $true
 
 Get-ADUser -Identity $displayName

Note, keep in mind that the SamAccountName aka "user logon name (pre-windows 2000)" has a maximum character length of 20 characters. So when validating your inputs you probably want to check that the entered value isn't too long, for instance

if ($samaccountname.length -gt 20)
{
   Write-Output "Error, entered username is longer than 20 characters"
   break
}
