从文本文件中提取每个用户的“成员”安全组列表

Question

I written the below PowerShell script to pull the list security for each user. All user list are inside the text file "ulist.txt" line by line. It not pull some user from that text file where as that really exist inside the directory.

Clear-Host
$ul = Get-Content -Path "C:\Users\username\Desktop\ulist.txt"

ForEach ($item in $ul){
$item = $item.toupper()
Write-Host ------------------------------------------------------------------ -ForegroundColor Yellow
Write-Host The user $item belongs to following security groups. -ForegroundColor Yellow
Write-Host ------------------------------------------------------------------ -ForegroundColor Yellow
$allgroups = Get-ADUser $item -Properties *  | Get-ADPrincipalGroupMembership | Select-Object name | Format-Table -HideTableHeaders | Out-String | ForEach-Object { $_.Trim("`r","`n") } 
$allgroups
Write-Host ------------------------------------------------------------------ -ForegroundColor Yellow 
}

Error:

Get-ADUser : Cannot find an object with identity: xxxxxxxx
Get-ADUser : Cannot validate argument on parameter 'Identity'. 
             The Identity property on the argument is null or empty.

I do not understand what is wrong in this script.

It only pull and showing only the default group "Domain Users" for some users not the other groups associated.

After modified a little bit when it was pulled and appended the user list, I did a little bit mistake. Instead of "select Name", I changed it to "select SamAccountName". Perfect, it displayed me what I was expecting.

Thank you Team.
