So you are really looking for a programmer to do the job for you ... ;(

Anyways: your requirement "last hour" can be ignored, as your log file only covers the last hour. So it is only

  1. Link user to connection.
  2. Count "SRCH=Q" per connection.
If you are looking for help here it would be good to
  1. Provide some of your own attempts.
  2. Provide a bigger sample to let people test code.
The following code is not production ripe as it depends on a number of assumptions based on your limited sample. 

use strict;
use warnings;

my %user;
my %conn;

while(<DATA>){
        my ($conn) = /conn=(\d+)\s/;
        my ($uid) = /uid=(.*?),/;
        $uid ? $user{$conn}=$uid : $conn{$conn}++;
}

for my $key ( keys %conn ) {
        print $user{$key}//"Unknown user";
        print ": $conn{$key} times in logfile\n";
}
__DATA__
[04/Jun/2013:13:06:13 -0600] conn=13570 op=14 msgId=13 - BIND dn="uid=
+xyz123,ou=People,o=xyz.com" method=128 version=3
