Response: 220- Welcome to Pure-FTPd [privsep] [TLS] - Response: 220-You are user number 9 of 50 allowed. It says "530 Login authentication failed". I tried active or default mode: didn't change anything.
Most programs will only have a single type, if any at all, i.e., ftpd(8) will always request the ftp type authentication, and su(1) will always request the su type authentication. The login(1) utility is special in that it may select an authentication type based on information found in the /etc/ttys file for the appropriate tty (see ttys(5) ).
