Proftpd Login problem with 530 error

I installed a ftp server, Proftp on a developing virtual system. It is on Centos 6 64bit. Install Proftpd with yum command.

When I use ftp client software to connect the ftp server, I got following error.
Response:   220 FTP Server ready.
Command:   USER davidyin
Response:   331 Password required for davidyin
Command:   PASS ******
Response:   530 Login incorrect.
Error:   Critical error
Error:   Could not connect to server

I checked the error log file and saw the following error message.

It is confused me so much and at the last I found the problem.
The reason I get the errors with the home dirs is because of selinux

I have to disable it and everything is OK now.
