[Vu Xuan Ngoc]

I am using qmail-ldap with qmail-ldap-20010301.patch
I creat a ldap entry:

dn: uid=media,ou=qmailusers,dc=vn
objectClass: person
objectClass: qmailuser
...
accountStatus: active
homeDirectory: /home/export/media
deliveryMode: ./maildir/
mailhost: newsletters.vnn.vn
mail: [EMAIL PROTECTED]
...

my config files
    +)host :    technical.vnn.vn:
        control/locals          technical.vnn.vn
                                      newsletters.vnn.vn
        control/rcpthosts      technical.vnn.vn
                                      newsletters.vnn.vn
        control/me               technical.vnn.vn
        control/ldapcluster    1
        control/qmqpservers    newsletters.vnn.vn

    +)host:        newsletters.vnn.vn
        control/me              newsletters.vnn.vn
        control/locals          technical.vnn.vn
                                      newsletters.vnn.vn
        control/rcpthosts      technical.vnn.vn
                                      newsletters.vnn.vn
