qmail-ldap pop3 auth problem

hi all,

i'm having an issue to use latest qmail-ldap patch on debian squeeze

ldap configured correctly
qmail-smtpd working find, all incoming emails accepted
qmail-pop3d is not working so i try to test with qmail-ldaplookup
qmail-ldaplookup able to search for stored emails with -m but not with -u

when i do:
/var/qmail/bin/qmail-ldaplookup -u info (or -u [email protected]), the
response are:
==================================================
Searching ldap for: (mail=info)
under dn: ou=accounts, dc=mydomain, dc=com
No entries found.

qmail-ldaplookup: fatal: qldap_first: no such object
