Not sure which way you want the grouping count1 or count2.

#!perl
use strict;
use Data::Dumper;

my %hash = (
 '33|srv2' => [
    'users','users','users',
    'admin','admin','admin',
    'manager','manager','manager' ],
  '27|rufserv3' => ['system'],
  '16|lbapp0112' => [
    'admin (priv1',
    ' priv2)' ],
  '34|srv2' => [
    'users', 'users', 'users',
    'admin', 'admin',
    'manager' ] );
  
  #print Dumper %hash;
  my %count1;
  my %count2;
  for my $key (keys %hash){
    ++$count1{$_}{$key} for @{$hash{$key}};
    ++$count2{$key}{$_} for @{$hash{$key}};
  }
  print Dumper \%count1;  
  print Dumper \%count2;
