G'day symgryph,
Here's my take on a solution:
#!/usr/bin/env perl
use 5.010;
use strict;
use warnings;
local ($/, $") = ("", ',');
my @fields = qw{user summary access group};
my $re = qr{ (?: ^user:\s(?<user>\S+)
| ^\s*summary\s"(?<summary>[^"]+)
| ^\s*access-level\s(?<access>\S+)
| ^\s*group\s(?<group>\S+) ) }mx;
while (<DATA>) {
my %data;
@data{keys %+} = values %+ while m{$re}g;
say "@{[ map { $_ // '' } @data{@fields} ]}";
}
__DATA__
user: myus44 [up]
------------
admin-state enabled
summary "Johnny Cash"
access-level group-defined
group mi-group [up]
user: jar1543 [up]
------------
admin-state enabled
summary "Lara Croft"
access-level group-defined
group jar-head [up]
user: myprivilegeduser [up]
-----------
admin-state enabled
access-level privileged
Output:
$ pm_1047505_regex.pl
myus44,Johnny Cash,group-defined,mi-group
jar1543,Lara Croft,group-defined,jar-head
myprivilegeduser,,privileged,
While this produces the output you indicated, you may want to revisit your requirements.
++Tux makes some very good points in this regard.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
