Problem: When trying to access the samba share from a Windows 2019 server or Windows 11/Windows 10 system, you get the "Wrong Password error". Command line gives a more specific error, with a code:

System error 86 - The specified network password is not correct.

Solution:

Add the following option into the Samba config file (/etc/samba/smb.conf):

ntlm auth = true

This should stop the wrong password prompts and allow the Windows system to access Samba.
