In the following examples assume dialin-server is the machine to which the modems and ISDN cards are connected. The second word is the password for this machine. It has to be in cleartext, so be careful about the permissions of this file and the directory where it is installed. I've provided the user test1 with the password test1passwd for testing purposes. Be sure to change the user name and the password or comment this entry, before you put this server in you production environment.
