Cant run ldapadd

[Karamat Adil IHMD <KaramatA@ih.navy.mil>]

Hi all,
   I am new at this openLdap stuff and just finally got it to work with
BurkeleyDB. Following is the LDIF file that I am trying to add , which is a
sample file form the tomcat web site to use with openldap:
----------------------
# Define a user named 'tomcat'
dn: cn=tomcat,dc=xxx,dc=com
cn: tomcat
userPassword: tomcat
sn: Tomcat User
objectClass: person

# Define a user named 'both'
dn: cn=both,dc=xxx,dc=com
cn: both
userPassword: tomcat
sn: Both User
objectClass: person

# Define an entry to base role searches on
dn: dc=roles,dc=xxx,dc=com
cn: roles
objectClass: person
sn: Roles Entry

# Define all members of the 'tomcat' role
dn: cn=tomcat,dc=roles,dc=xxx,dc=com
cn: tomcat
objectClass: groupOfUniqueNames
uniqueMember: cn=tomcat,dc=xxx,dc=com
uniqueMember: cn=both,dc=xxx,dc=com
------------------

OK it adds the first two entries i.e tomcat and both and then when it tries
to add the third entry it gives the following message :

adding new entry "dc=roles,dc=xxx,dc=com"
ldapadd: update failed: dc=roles,dc=xxx,dc=com
ldap_add: No such attribute (16)
        additional info: naming attribute 'dc' is not present in entry


What am I doing wrong ????
Thanks,
Adil
