Hi, we try to join the Windows 8.1 pro client with samba4. But we can not establish the connection with windows client. I refered this link http://www.windowsecurity.com/articles-tutorials/misc_network_security/Secure-SMB-Connections.html, but i am not able to succeed to authenticate the windows 8.1 pro with samba4. Please suggest me HOWTO implement the proper SMB security for windows 8.1 pro and windows 10. In future, we would like to test the windows 10 as well. Is there any other tool like like-wise open/pgina will help me to authenticate the windows 8.1 pro and windows 10. Please give your valuable feedback. It will help us to implement the opensource samba4 alternate to Active Directory Services. -- with regards Ashok Kumar J
