Trouble implementing a hierarchial namespace

[Ørnulf Nielsen <on@lincom.no>]

I'm trying to implement the following namespace:

            _______
           | dc=no |
            -------
          _____|_____
         | dc=lincom |
          -----------
               |
       -------------------
 _____|_____      ________|_________
| ou=people |    | ou=psudoaccounts |
 -----------      ------------------



---[slapd.conf]---
schemacheck     on
defaultaccess   read


database        ldbm
cachesize       1000
dbcachesize     100000
directory       /var/run/openldap-ldbm/no/lincom

index           cn
index           sn,uid eq,sub,approx
index           default none

suffix          "dc=lincom,dc=no"
rootdn          "cn=Manager,dc=lincom,dc=no"
rootpw          secret
lastmod         on
readonly        off
---


---[lincom.ldif]---
dn: dc=lincom,dc=no
objectClass: top
objectClass: domain
dc: lincom
---

ldapadd -D 'cn=Manager,dc=lincom,dc=no' -W -f lincom.ldif

works just fine

---[people.ldif]---
dn: ou=people,dc=lincom,dc=no 
objectClass: top
objectClass: organizationalUnit
ou: people
---

---[psudoaccounts.ldif]---
dn: ou=psudoaccounts,dc=lincom,dc=no 
objectClass: top 
objectClass: organizationalUnit 
ou: psudoaccounts
---

ldapadd -D 'cn=Manager,dc=lincom,dc=no' -W -f people.ldif

and

ldapadd -D 'cn=Manager,dc=lincom,dc=no' -W -f psudoaccounts.ldif


exits with the following error message:
	ldap_add: No such object


Obviously, I've done something wrong :-)
