VSFTPD 530 Login incorrect

Have you ever met a problem with installing a new FTP server using VSFTPD on CentOS?

Here is my vsftpd.conf file

local_enable=YES
write_enable=YES
pam_service_name=vsftpd
connect_from_port_20=YES
listen=YES
pam_service_name=vsftpd
xferlog_std_format=NO
log_ftp_protocol=YES
chroot_local_user=YES

And monitor vsftp.log:

Mon Sep 13 23:34:44 2010 [pid 19243] FTP response: Client "10.0.1.138", "220 (vsFTPd 2.0.5)"
Mon Sep 13 23:34:44 2010 [pid 19243] FTP command: Client "10.0.1.138", "USER dwelch"
Mon Sep 13 23:34:44 2010 [pid 19243] [dwelch] FTP response: Client "10.0.1.138", "331 Please specify the password."
Mon Sep 13 23:34:44 2010 [pid 19243] [dwelch] FTP command: Client "10.0.1.138", "PASS <password>"
Mon Sep 13 23:34:44 2010 [pid 19242] [dwelch] FAIL LOGIN: Client "10.0.1.138"
Mon Sep 13 23:34:45 2010 [pid 19243] [dwelch] FTP response: Client "10.0.1.138", "530 Login incorrect."

Here is the solution:

vi /etc/pam.d/vsftp

comment #auth required pam_shells.so

service vsftpd restart

pam_shells.so means that only users with shells access should be allowed so that’s why needs to be commented
