ldap_add: Naming violation (64)

["Tibbetts, Ric" <ric.tibbetts@ngc.com>]

Can anyone shed some light on this?
I'm "trying" to add the auto.home entries, and I'm getting a naming 
violation on an entry that I thought was good. Here's the error:

------------------------
adding new entry 
"cn=/,nisMapName=auto.home,ou=Services,o=eng,l=mlb,dc=ldap-test,dc=com"
ldapadd: update failed: 
cn=/,nisMapName=auto.home,ou=Services,o=eng,l=mlb,dc=ldap-test,dc=com
ldap_add: Naming violation (64)
        additional info: value of naming attribute 'cn' is not present 
in entry
------------------------

And, here's the ldif I'm trying to add:

------------------------
dn: nisMapName=auto.home,ou=Services,o=eng,l=mlb,dc=ldap-test,dc=com
objectClass: top
objectClass: nisMap
nisMapName: auto.home

dn: cn=/,nisMapName=auto.home,ou=Services,o=eng,l=mlb,dc=ldap-test,dc=com
objectClass: nisObject
cn: *
nisMapEntry: mengsu01:/export/home/&
nisMapName: auto.home
------------------------

Thoughts anyone?

Thank you!
