I have just installed the KDE edition of linux mint 14.
I read on the internet how to join a windows workgroup, however when I try to edit the etc/samba/smb.conf file, I do not have the permission to save the changes. I don't know the administrator password (it didn't ask me during the installation).
If I go to the user management, It tells me that /usr/bin/kcmshell4 userconfig needs administrative privileges and asks mo for a password. The current (and only existing user) password does not work and no blank password.
How can I get the passwords?
