没有访问权限的文件夹的 Powershell Get-Acl

Question

I wrote a script, which gives me all the permissions of a folder + subfolders for a user/group. However, the script only works, if my user has at least read permissions on all these folders. If he has no permissions, get-acl is denied. Is there any way to work around this, as I don't want to manually switch my user everytime I execute this script.

Can I execute a powershell script with a different user? And if yes, how?

Thank you in advance, Colin

You have a few options that I can think of:

Option 1: Create a helper file with the actual code you want to run and call it script.ps1 for instance:

    [array]$users = "user1","user2","user3"

    foreach($user in $users){
        $creds = Get-Credential -UserName $user -Message "Enter the Users Password"
        $Session = New-PSSession -Credential $creds
        Invoke-Command -Session $Session -FilePath C:\Path\to\some\script.ps1
    }

Option 2: Run a job for each user. After every task is finished, the new user credentials will be asked. Just add the code to the scriptblock

[array]$users = "user1","user2","user3"

foreach($user in $users){
    $creds = Get-Credential -UserName $user -Message "Enter the Users Password"
    $target = $user
    $job = Start-Job -scriptblock {
    param ($username)
        Get-Acl C:\Users\$user #Bla bla the rest of your script
    } -Args $user -credential $creds
    do{
        #Wait for the job to finish
    }until($job.State -ne "Running")
    Write-Host "Job finished with state $($job.State)"
}

Hope this helps!

Note that the creds object can also be automated, if you don't wish to type all the time. (Security principles not taken into account ;) )

$users = @()
$users += @{
    username = "User1"
    password = "Pass123!"
}
$users += @{
    username = "User2"
    password = "Pass123!"
}

foreach($user in $users){
    $creds = New-Object System.Management.Automation.PSCredential($user.username,($user.password | ConvertTo-SecureString -AsPlainText -Force))
    #Add the rest of the script from the chosen option
}
