and here junit :

             string user = "samba";              string pass = "yesplaintextpassword";              string sharedfolder = "home/samba";              string path = "smb://myip/" + sharedfolder + "/test.txt";              ntlmpasswordauthentication auth = new ntlmpasswordauthentication("s55-app01-dev", user, pass);              try {                smbfile smbfile = new smbfile(path, auth);                smbfileoutputstream smbfos = new smbfileoutputstream(smbfile);                inputstream = smbfile.getinputstream( ):                system.out.println("pas d’erreur");              } catch (exception e) {                system.out.println(e.getmessage());              } 

i know password good, tried , without domain name. tried without /home sharedfolder variable.

i tried add :

        config.setproperty("jcifs.smb.client.useextendedsecurity", "false");         config.setproperty("jcifs.smb.lmcompatibility", "5");         config.setproperty("jcifs.smb.client.disableplaintextpasswords", "false"); 

with true, or false, value 0 (oldest authentification) 5 (newest authentification protocol if understand correctly)/

i don't know next. administrator told me linux server has no firewall or block on port 139 , 145.

i'm on windows 7, samba-4.5.1 , jcifs 1.3.3.

thanks in advance tips or answer (and sorry english, it's not native language).
