you must first add a linux user then add the samba user.
Must be the same name and pass
I am running Red-Hat 8.0
I add my user through the GUI.
Then run smbpasswd -a username
It should prompt for password.
You must also creat a root smb user
to do this
smbpasswd -a
Now that you have your users you can get to work on your smb.conf
This is under /etc/samba
Edit the file search this forum for different configs that is how I was able to make mine work.
when you think you have the smb.conf right try and add the PC to the domain.
