help with qmail - ldap

The site where it is supposed http://qmail.bayour.com/patches_ldap/ qeu this
qmail-ldap-control is not available, they know from somewhere else where it
may be a patch for download, or if they could help me with the error sale.

ldap works fine and adds the users well, but when I use qmail-ldaplookup
getting an error which says this:

[root@qmail ~]# /var/qmail/bin/qmail-ldaplookup -d 255 -u postmaster

No mail delivery does not create the directory for messages.

Or have any idea what could be my mistake, if you like I can send my
configuration.
