How do you check a 'bind' in LDAP?

LittleGreyCat has asked for the wisdom of the Perl Monks concerning the following question:

Esteemed Monks

I am trying to learn Net::LDAP

I wrote a little ditty which worked, then stopped working.

I tracked the problem down to credentials.

I have been following the examples and use the form:

$ldap = Net::LDAP->new( 'ldap.umich.edu' );
# bind to a directory with dn and password
$ldap->bind( 'cn=root, o=University of Michigan, c=us',
                      password => 'secret'
                    ) or die "Unable to bind $!\n";
[download]

The problem seems to be that if an authenticated bind fails, then an anonymous bind is allowed, so the 'bind' is successful (just not as successful as I hoped).

I have found a 'whoami' extension, in Net::LDAP::Extension::WhoAmI, but the directory I am binding to doesn't seem to support extensions.

So how do I check to see if I am bound as an anonymous or authenticated user?

TIA

Hey The object will hold the error code if there is one, so you can check it. Here's an excerpt from the FAQ: http://ldap.perl.org/FAQ.html "Most methods in Net::LDAP return a Net::LDAP::Message object, or a sub-class of that. This object will hold the results from the server, including the result code. So, for example, to determine the result of the bind operation. `$mesg = $ldap->bind( $dn, password => $passwd ); if ( $mesg->code ) { # Handle error codes here }` [download] " Hope this helps, Hays	[reply] [d/l]

Hays, Many thanks - I was just coming back to update my question with a "found it" because another bit I was reading just sank in. My code now has: $result->code && die "\nSomething bad happened : ", $result->error ; This works fine; I now feel dumb for not spotting it sooner.
