请好好先生帮我看看怎么本地用户登录密码正确与否都登录不了呢？

sun_star

各配置文件如下，本地用户怎么登录都显示为530 Login incorrect.Login failed，我估计是pam认证有问题，可我找不出来，帮一下：
etc/vsftpd.ftpusers
# Users that are not allowed to login via ftp
root
bin
daemon
adm
lp
sync
shutdown
halt
mail
news
uucp
operator
games
nobody

/etc/vsftpd.user_list
# vsftpd userlist
# If userlist_deny=NO, only allow users in this file
# If userlist_deny=YES (default), never allow users in this file, and
# do not even prompt for a password.
# Note that the default vsftpd pam config also checks /etc/vsftpd.ftpusers
# for users that are denied.

好好先生

看一下你的vsftpd的状态。service vsftpd status
