V4 LDAP Authentication

[Cantor, Scott]

Chaining validators in V4 implies you don't have a list of URLs in the ldapURL. You'd have them explicitly configured in a chain in the XML file. The chaining model will not only use the last one in the chain, it defaults to success if at least one works, trying them in order. 'sufficient" is the JAAS term.

As far as how the code itself behaves within a single link of a chain, if it no longer handles particular settings or approaches, that's a bug or an issue to be documented. If it supported multiple URLs in a given LdapAuthenticator before, it should now.
