My mistake, try something like this

$user = "root" 
$pswd = "password"
 
Get-VMHost  | %{
  $esx = Connect-VIServer $_.Name -User $user -Password $pswd
  Get-VMHostAccount -Server $esx |
  Select @{N="Host";E={$esx.Name}},@{N="Uid";E={$_.ExtensionData.Id}},Id,@{N="Name";E={$_.ExtensionData.FullName}}
  Disconnect-VIServer -Server $esx -Confirm:$false
}
