Windows 10 login information for accessing samba share protected directory located on Ubuntu 18.04
Matthew Martinez 
Can someone give an example of login information (username and password) on Windows 10 for the samba protected directory which is located on Ubuntu 18.04?
I have created a user in Ubuntu and added smbpasswd for him, but I don't know how the username should look to be able to get into the protected directory.
Accessing a public directory from Windows is working without a problem.

As for this specific error message:
Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
The problem here is that when a user on Windows first makes contact with a server it automatically passes that users' local login username. If you have a public share it remembers that it took that username successfully. When you try to connect to a private share and don't pass the exact same username and password, it thinks you are trying to access with another name.
Some workarounds:
1) Map the Windows user to the local Linux user - this is useful for Win10 users who log into their systems with a Microsoft account.
Create a file at
/etc/samba/smbusersMap the local Linux user to the Windows user by adding the conversion to the file. For example:
luci =
john = "John Smith"- Then add a reference to the map in
/etc/samba/smb.confin the[global]section:
username map = /etc/samba/smbusers- Finally restart smbd:
sudo service smbd restart
2) Make another connection to the Linux server
Windows can address a Linux server in two (three in Win10) different ways. By hostname, by ip address, or by mDNS name (Win10 only):
\\ubuntu\Protected
\\192.168.0.100\Protected
\\ubuntu.local\ProtectedEven though all of these point to the same machine, Windows sees them a three separate hosts.
3) Map the "network drive"
When mapping a drive, select the "connect using different credentials" option.
