Reading this kind of data is best done IMHO by first reading all of the data into an array of hashes (one hash per user) and then print in the desired format. This way you get nice and clean code with one line for each line of your data: 

use strict;
use warnings;
my @data;
while(<DATA>){
        push @data, { 'user' => $1 }  if /^user: (\w+)/;
        $data[-1]{'summary'}     = $1 if /summary\s+"(.+)"/;
        $data[-1]{'accesslevel'} = $1 if /access-level\s+(\S+)/;
        $data[-1]{'group'}       = $1 if /group\s+(\S+)/;
}
for my $user (@data){
        print join ',', map { $user->{$_} // '' } qw(user summary acce
+sslevel group);
        print "\n";
}
