connexion ldap impossible

[ps2ali]

Bonjour,
je vais dire une chose qui est vraiment etonnant, j'en suis au 15 éme jour et j'ai pas trouvé de solution de mon probléme;
alors je vais essayer de décrire ce qui se passe pour mon projet de fin d'études, une partie de mon projet est:installation et configuration de ldap. j'ai travaillé avec la fedora core 6.
je tappe sous shell la commande:

Code :

ldapadd -x -W -D "cn=root,dc=sanad,dc=com" -f test.ldif

afin d'ajouter une entrée.
mais le message:

ldap_bind:invalid credentials

pour bien mettre les points sur les i voila mes fichiers de configurations:
mon fichiers slapd.conf:

#        Allow authenticated users read access
#        Allow anonymous users to authenticate
#    Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#    by self write
#    by users read
#    by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!
