centos – VSFTPD 530登录不正确

我正在尝试在CentOS 5.3 x64上设置vsftpd服务器.我无法让任何本地用户登录工作.这是我的vsftpd.conf： @H_404_1@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

这是vsftp.log的输出：

@H_404_1@mon Sep 13 23:34:44 2010 [pid 19243] CONNECT: Client "10.0.1.138" 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."

并且安全日志的输出：

@H_404_1@Sep 13 17:40:50 intra vsftpd: pam_unix(vsftpd:auth): authentication failure; logname= uid=0 euid=0 tty=ftp ruser=dwelch rhost=10.0.1.138 user=dwelch

看起来pam没有验证用户身份.这是我的/etc/pam.d/vsftp文件：

@H_404_1@#%PAM-1.0 session optional pam_keyinit.so force revoke auth required pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed auth required pam_sHells.so auth include system-auth account include system-auth session include system-auth session required pam_loginuid.so

任何人都能看到我错过的东西吗？谢谢.
