mod_vcard_ldap is dumb

Greetings All.

How do I setup mod_vcard_ldap? I is not mentioned in the guide.html file nor I could find anything useful here. In ejabberd.conf I've got such a line

  {mod_vcard_ldap, [{host, "jud.asdf.pl"}]},

and when i try to *search* for user zxcv in jud.asdf.pl

                                       {mod_vcard_ldap,
                                           '-search/1-lc^0/1-0-',
                                           2},
                                       {mod_vcard_ldap,search_result,3},
                                       {mod_vcard_ldap,do_route,3},
                                       {mod_vcard_ldap,loop,1}]}

while zxcv is one of users in the directory. LDAP server works rather fine. I think so because other applications (eg. samba) do not complain at all and work correctly.

By the way when I try to get "User Info" (I use Psi) of a specific user everything works just as it should.

Have a nice day.
