How can I configure mod_vcard_ldap correctly?

Hello,

Is there any documentation on parameters that mod_vcard_ldap accepts?
I've compiled ejabberd from svn (revision 434) yesterday.
I can authenticate through LDAP database on localhost, it works fine.
Nevertheless mod_vcard_ldap does not function correctly, the error message in log is the same to
http://www.ejabberd.im/node/401
(actually my post is duplicate to that one :) ).

mod_vcard_ldap is said to be fixed in the latest SVN revision, what do I need to pass to it in order to get it working?
The current configuration is

{mod_vcard_ldap, [{host, "localhost"}]}

Error message that is logged during attempt to see user details is:

                                             {eldap_search,
                                                 wholeSubtree,
                                                 undefined,
                                                 {equalityMatch,
                                                     {'AttributeValueAssertion',
                                                         undefined,
                                                         "user1"}},
                                                 [],
                                                 false,
                                                 0}}]}}

My assumption is that there's something wrong/misconfigured in

{eldap_search, wholeSubtree, undefined, 
    {equalityMatch,{'AttributeValueAssertion',undefined,"user1"}},
    [],false,0}

too many 'undefined' parameters there :)
