Help creating admin and user

[Mário Gamito <gamito@gmail.com>]

Hi,

I'm trying to create the admin and a user, but i can't.

I'm using this base.ldif file:
-------------------------------------------------
dn: cn=Mario Gamito, dc=sincity, dc=lan
cn: Mario Gamito
mail: gamito@www.sincity.lan
objectClass: qmailUser
mailHost: www.sincity.lan
mailMessageStore: /var/qmail/maildirs/gamito
mailQuotaSize: 1000000
qmailUID: 7798
qmailGID: 2108
uid: gamito
userPassword: {MD5}2EBkyEbKsYUpC/T/5VFuOg==
--------------------------------------------------

with the command:
ldapadd -x -D "cn=root,dc=sincity,dc=lan" -w secret -f base.ldif

but i get the error:
adding new entry "cn=Mario Gamito, dc=sincity, dc=lan"
ldap_add: Object class violation (65)
        additional info: entry has no objectClass attribute


Can someone give me a hand on this, please ?

Thanks in advance.

Warm Regards,
Mário Gamito
