Humble and grateful, your insightful observation to chomp has revived this perl program to a higher level. The resultant output remains divided by a dash line; and Data::Dumper and print OUT, these lines are not working as buildAD.ldif only gets ,,bless'' coding structure. foreach $dn ($dn->entries) { push @attr, $dn->dump; } #$Data::Dumper::Purity = 1; #$Data::Dumper::Deepcopy = 1; my $ev = Data::Dumper->Dump($dn, qw(dn)); print OUT $ev; }
