Committed to HEAD. Command-line clients now use DNS SRV to look up the host names related to a DN and build a list of URIs for subsequent use. To trigger, use -H "<proto>:///DN". The <host> portion must be empty, and a DN must be present. The DN must be in the "dc=<component>" form; it's turned into a domain and the host list is looked up using DNS SRV. After that, a list of URIs is built using the returned host/ports, and using <proto> as the LDAP scheme.

Thank you! I've forwarded this information to the original Debian bug reporter who was interested in the feature in the hopes that he'll be able to test and provide feedback on the implementation.
