Newbie needs help!

[Patrick Ouellet <lazypete@aei.ca>]

Im trying to build my first LDAP server to authetificate mail user
with cyrus imapd.

Im using FC3 with the provided binaries:
version 2.2.13

I setuped slapd using instruction found in LinuxJournal
Issue 111 and 112.

Here is my problem.
I get this error when I try to add my organizational entry:

ldap_add: Naming violation (64)
       additional info: value of naming attribute 'dc' is not present 
in entry

Here is my ldif file
dn: dc=mit,dc=homelinux,dc=org
objectclass: dcObject
objectclass: organization
o: Men in Tux inc.

Can anyone shed some light on my problem.

Thanx everyone, and please keep up the good work!
