Forum Linux.général LDAP + Samba : "utilisateur introuvable" sur Windows XP

Bonjour à tous,

J'ai suivi ce tuto pour gérer un serveur LDAP + Samba sur Ubuntu 8.04 et j'ai un petit problème...

Lorsque j'essayes de me loguer sous Windows avec mon LDAP, j'ai un message d'erreur : "

Apparemment, ce qui fous les bordel c'est ce "can't open username map /etc/samba/smbusers. Error No such file or directory "...

Mais je vois pas comment remédier à cela...

Des idées ? :S

Merci à tous.
