Unknown Windows Network at my Fedora machine

Thank you very much for teaching me new levels of entering Samba by CLI .
I do not understand if I shall create a new user sudo smbpasswd -a Jonas as a guest of the allready existing user [TemplePusher@jonas-bloch-riisgaard ~]

[TemplePusher@jonas-bloch-riisgaard ~]$ sudo firewall-cmd --reload
success
[TemplePusher@jonas-bloch-riisgaard ~]$ sudo smbpasswd -a Jonas
New SMB password:
Retype new SMB password:
Failed to add entry for user Jonas.
[TemplePusher@jonas-bloch-riisgaard ~]$ sudo smbpasswd -a Jonas
[sudo] password for TemplePusher: 
Sorry, try again.
[sudo] password for TemplePusher: 
New SMB password:
Retype new SMB password:
Failed to add entry for user Jonas.

As I follow the example I do fail because of lack of understanding. As I understand the Quick docs - How to create a Samba share. I will create a guest user and NOT a new user with the sudo rights ?
