note CountZero How can we know why things get printed twice? The code you showed does not even have a <c>print</c> statement!<p><blockquote><em>I am pushing a user name and an array of AD groups for that user name into a hash of arrays: Code: </em><c>push (@{$newgrouphash{"$newdn"} },"$newgroup")</c></blockquote>You are not pushing an array of AD groups into a HoA. You are pushing the stringified version of a scalar into your HoA. For a start, drop all the double quotes around your variables. They serve no purpose. Then check whether <c>$newgroup</c> indeed contains a reference to your array of AD groups.<p>And finally show us the code you use to output this data.<!-- Node text goes above.
