note salva Could you show us the code where <c>$system</c> is populated? <p>Also, use Devel::Peek to print the internals of some of its values and let us see the output. For instance: <code> use Devel::Peek; ... $system{some_host}{some_user} = $ldap->whatever(); Dump($system{some_host}{some_user}); </code> 490213 490230
