Windows file sharing fix

And now you have successfully configured your Linux server to get authenticated via AD, Hooray!

Wait a minute, why can't I connect to my \\ files on Linux from Windows?

Here's the changes you need to make on your Windows Server local policy:-
1.Open the Run command and type "secpol.msc".

2. Click on "Local Policies" --> "Security Options"

3. Navigate to the policy "Network Security: LAN Manager authentication level" and open it.

4. Change the policy to "Send LM and NTLM – use NTLMV2 session security if  negotiated".
