Newbie question: adding to database

["John Green" <green@blueheronbio.com>]

I'm new at this, and have tried to find the info first before hitting this
list, if this is the right list, but I'm stuck. I've set up (on RH 7.2)
OpenLDAP 2.0.11 with Kerberos/SASL/SSL (thanks Turbo), and have created a
database via a file named newentry1, contents below. I can't seem to add any
additional entries with the exception of objectClass=top in a file called
newentry1a, contents below.  I tried adding file newentry1b, with different
contents, and get the same error.  Is there a specific order that I have to
add attributes and objectClasses in?  The error I get is:
ldap_modify: Object class violation
additional info: missing required attribute
I also added a copy of my slapd.conf below.  Any help would be appreciated.
Thanks  --  John
