You should use the "edit your code" link that appears after the source listing to fix bad nodes rather than reposting them. If that link doesn't appear because the html is too severely corrupt you can still edit the node by constructing the following perlmonks url:

/index.pl?displaytype=edit&node_id=56537&lastnode_id=56537

That example uses the node_id of your first attempt to post the LDAP Searcher. Just add the domain you usually use to access perlmonks so your cookie works.
