I don't know the Cygwin solution, but here's a short PowerShell function
that will do it:

function Resolve-AccountName {
  param(
      [Parameter(Mandatory)]
      [Security.Principal.NTAccount]
      $name
  )
  $sid = $name.Translate([Security.Principal.SecurityIdentifier])
  if ( $null -ne $sid ) {
    $sid.Translate([Security.Principal.NTAccount]).Value
  }
}
