adding usernames

[Robert Williams <bob@bob.usuhs.mil>]

I'm looking for some guidance
to help me add names and passwords to
an ldap server.  (I realize these  are somewhat
dump questions.)

My slapd.conf is boilerplate:

[root@rw openldap]# more slapd.conf
#
# See slapd.conf(5) for details on configuration options.
# This file should NOT be world readable.
#
include         /etc/openldap/slapd.at.conf
include         /etc/openldap/slapd.oc.conf
schemacheck     off
#referral       ldap://root.openldap.org/

pidfile         /var/run/slapd.pid
argsfile        /var/run/slapd.args

# ldbm database definitions

database        ldbm
suffix          "dc=usuhs, dc=mil"
suffix          "o=USUHS, c=US"
directory       /usr/tmp
dbcachesize 5000000
rootdn          "cn=Manager, dc=usuhs, dc=mil"
#rootdn         "cn=Manager, o=USUHS, c=US"
rootpw          uhnuhnuhaaa
# cleartext passwords, especially for the rootdn, should
# be avoid.  See slapd.conf(5) for details.
directory       /usr/tmp

_______________
I've added the following file (myldif.ldif)
using " ldapadd -D "cn=Manager, dc=usuhs, dc=mil" -w  uhnuhnuhaaa <
new.ldif ":

[root@rw openldap]# more myldif.ldif
dn: dc=usuhs, dc=mil
dc: usuhs
o: USUHS
objectclass: organization
objectclass: dcObject

dn: cn=Manager, dc=usuhs, dc=mil
cn: Manager
sn: Manager
objectclass: person

_____________________

I can add the following file (new.ldif):

dn: cn=Robert Williams, dc=usuhs, dc=mil
cn: Robert
sn: Williams
objectclass: person
____________________
but the Netscape ldap client returns
with: ...ldap error "no such object" (0x20)
when searching for names containing any
part of "Robert Williams"
______________________

Why can't I add the following file (new2.ldif):

dn: cn=Robert Williams, o=USUHS, c=US
cn: Robert
sn: Williams
givenname: Bob
objectclass: person

I guess I'm looking for a simple model
or tutorial
for putting together a ldap database with
usernames and passwords, that is
username searchable
(except for passwords)
and useful for ldap based authentication
(pam-ldap, etc).
