Problem installing slapd

["Jean-Pierre LATOUR" <jplatour@sinorg.fr>]

Sorry, 

I have a lot of difficulties installing ldap library and I really don't knw
what could happen.
I try to install the servers and to do some test.
When i do a query like 
ldapsearch cn="*" 
	the result is : ldap_serach no such object
and 
ldapadd < newentry
with newentry containing :
dn: cn=LATOUR Jean-Pierre, o=sinorg,c=FR
objectclass: top
objectclass: person
objectclass: quipuObject
objectclass: kerberosSecurityObject
cn: LATOUR Jean-Pierre
cn: Jean-Pierre LATOUR
cn: JPLATOUR
sn: jplatour
description: Manager of the directory
userpassword: secret

  dn: cn=JeanPierr, o=sinorg, c=FR
           objectClass: person
           cn: JeanPierr
           cn: JP
           sn: Jensen
           title: the world's most famous mythical manager
           mail: bjensen@terminator.rs.itd.umich.edu
           uid: bjensen

the result is also	lpad_add	no such object.

Do you have any idea ?

Thanks
