LinuxQuestions.org - su prompts for a password when no such is set

Hello everyone,

Story: i use Fedora9 and i want to set up a FTP server whithout creating a home dir for each and every user, i want them to share 1 home dir. All users are in one group.

Problem: i write the following:

Code:

root# useradd -d /home/ftp_home -g ftp_users -M user1

root# useradd -d /home/ftp_home -g ftp_users -M user2

root# su - user1

user1$ su - user2

Password: 

su: incorrect password

user1$

This happens no matter what password i enter. I can only log into user2 if i type user1$ logout ; root#su - user2
