Hello, i've got a problem with a linux client joined to a samba3 domain. I join it with this command "net rpc join -S 192.168.151.237 -U admin" after configuring winbind in smb.conf. I follow this french tuto : http://doc.ubuntu-fr.org/tutoriel/comment_integrer_machine_ubuntu_domaine_nt_samba It works fine, but after a few days, it's impossible to login. It seems that the machine account expired. I have to use again the "net rpc join" command to make it works. I have this problem only with linux clients, all my windows clients works fine. How i could find what is the problem ? Thanks for your help Pascal
