additional info: value of naming attribute 'dc' is not present in entry

["Brian Bisaillon" <brianb@hive.com>]

I used the following this time to get things running: 
 
suffix          "dc=itarchitect,dc=ca" 
rootdn          "cn=Manager,dc=itarchitect,dc=ca" 
 
I ran ldappasswd to generate a new password. Once I had that password, I ran 
ldappasswd -A -S and pasted the password that ldappasswd gave me when I ran it 
the first time to get pass the old password. When ldappasswd prompted me for the 
new password, I pasted the SHA hash of my new password. The same SHA hash 
appears in my slapd.conf file. Now, I am able to authenticate when running ldapadd. 
 
The problem I have now is that when I run the following command: 
ldapadd -x -D "cn=Manager,dc=itarchitect,dc=ca" -W -f itarchitect.ca.ldif 
 
I get the following error: 
 
root@linux:/usr/local/etc/openldap# ./ldifadd 
Adding LDIF entries to LDAP directory... 
Enter LDAP Password:

Here is what it looks like in /var/log/debug:

Here is my LDIF: 
 
# File: ldif00.ldif 
 
# Root node 
dn: dc=itarchitect,dc=ca 
objectClass: top 
objectClass: organization 
objectClass: dcObject 
o: itarchitect.ca 
dc: itarchitect.ca 
 
# The R&D branch node 
dn: ou=R&D,dc=itarchitect,dc=ca 
objectClass: organizationalUnit 
ou: R&D 
 
# The Super-User's node 
dn: cn=Manager,dc=itarchitect,dc=ca 
objectClass: organizationalRole 
cn: Manager 
 
After that I have an entry for a person that would be a member of the above OU. 
 
What is the problem with my LDIF? Again, apologies but I am a newbie and yes I 
have read a lot of documentation including the documentation on the web site.
