$ smbpasswd
Old SMB password:
New SMB password:
Retype new SMB password:
Could not connect to machine 127.0.0.1: NT_STATUS_LOGON_FAILURE
One suggestion was to add the user to samba
smbpasswd -a frank
This brought up list of options, should it tell me user added?
Samba quick start guide use smbadduser name:name but that gave command not found
Did that but when I retry to change password I get same error message.
Browsing around it suggests that this error message is that you did not enter old password, as it is a new install I presumed it to be blank and googling samba default password came up with 1234 as default password, so tried that in the old SMB password... same error.
