During the installation of the new computers in my old school, there was the problem that /etc/smbpasswd could not be created by a script from /etc/shadow. SAMBA's built-in password synchronization did not work either. In order to prevent the users from having to type in their new passwords more than twice, a program needed to be written which handles the two changes all at once: frgpasswd.
I have chosen the name frgpasswd because my school's name is Fritz-Reuter-Gymnasium.
