(How many colons? :-) Close, but try this instead:

use Net::LDAP::Util qw(ldap_error_name);
...
print "Error: ", ldap_error_name($result->code), "\n" if $result->code;

This is something the documentation could be clearer about.

The error() method only returns to you the error text that the LDAP 
server filled in. However in the LDAP protocol, the error text is 
optional, and does not have to be filled in. Most servers do not, and 
you should not write code to ever depend on particular values in this 
field.

If you're curious, see the penultimate paragraph of RFC 2251 section 
4.1.10.

The only portable thing you can do is to get the error code() and print 
that. Servers *have* to return a correct result code :-)

Mark's pointed out the utility function to convert the result code to a 
more meaningful error message...
