Powershell Script to export permissions on entire Domain or OU

Question

Hello,

I'm seeking assistance with a PowerShell script to export permissions within Active Directory, either for the entire domain or for a specific Organizational Unit (OU), and save the output in CSV format.

Could someone kindly provide such a script?

Thank you in advance.

Regards,

Raj

Try the following

Import-Module ActiveDirectory

function Get-ADPermissions {
    param (
        [string]$TargetDN
    )
    $acl = Get-ACL -Path "AD:$TargetDN"
    $permissions = $acl.Access | ForEach-Object {
        [PSCustomObject]@{
            IdentityReference = $_.IdentityReference
            ActiveDirectoryRights = $_.ActiveDirectoryRights
            AccessControlType = $_.AccessControlType
            ObjectType = $_.ObjectType
            InheritanceType = $_.InheritanceType
            InheritedObjectType = $_.InheritedObjectType
        }
    }
    return $permissions
}

$targetDN = "DC=yourdomain,DC=com" # For the entire domain
# $targetDN = "OU=YourOU,DC=yourdomain,DC=com" # For a specific OU

if ($targetDN -match "^DC=") {
    $ouList = Get-ADOrganizationalUnit -Filter * | Select-Object -ExpandProperty DistinguishedName
} else {
    $ouList = @($targetDN)
}

foreach ($ou in $ouList) {
    $permissions = Get-ADPermissions -TargetDN $ou
    foreach ($perm in $permissions) {
        $result += [PSCustomObject]@{
            OU = $ou
            IdentityReference = $perm.IdentityReference
            ActiveDirectoryRights = $perm.ActiveDirectoryRights
            AccessControlType = $perm.AccessControlType
            ObjectType = $perm.ObjectType
            InheritanceType = $perm.InheritanceType
            InheritedObjectType = $perm.InheritedObjectType
        }
    }
}

$result | Export-Csv -Path "C:\ADPermissions.csv" -NoTypeInformation
