Another hint is use the following, which I think is more readable :-)
my $dn = 'corpid=xxxxxx,ou=people,o=corp';
my ($ou) = $dn =~ /ou=(.*?),/;
print "ou = $ou\n";
From perldoc perlre:
Sometimes minimal matching can help a lot. Imagine you’d like
+to match
everything between "foo" and "bar". Initially, you write somet
+hing
like this:
$_ = "The food is under the bar in the barn.";
if ( /foo(.*)bar/ ) {
print "got <$1>\n";
}
Which perhaps unexpectedly yields:
got <d is under the bar in the >
That’s because ".*" was greedy, so you get everything between t
+he first
"foo" and the last "bar". Here it’s more effective to use mini
+mal
matching to make sure you get the text between a "foo" and the
+first
"bar" thereafter.
if ( /foo(.*?)bar/ ) { print "got <$1>\n" }
got <d is under the >

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).
