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".
