For reference, here is the URL mentioned on this list during the last
discussion of a CVE assignment related to LDAP and an empty string:

  http://securitysynapse.blogspot.ca/2013/09/dangers-of-ldap-null-base-and-bind.html

The Cherokee vulnerability here is essentially a misinterpretation of
an LDAP server response. Cherokee should be expecting the semantics:

  - If I send a username and a non-empty password, a successful bind means
    that that's the correct password for the user

  - If I send a username and an empty password, a successful bind means
    that (A) that's not the correct password for the user and (B)
    the LDAP server probably happens to allow unauthenticated information
    retrieval that might or might not be intentional

Instead, Cherokee incorrectly assumes that the semantics are:

  - If I send a username and any password (empty or non-empty), a
    successful bind means that that's the correct password for the user

Use CVE-2014-4668.
