vsftp PAM认证总是过不去
各位大侠，求指教一二：..到底错在哪了？？
准备通过vsftpd+mysql+pam实现一个完善点的FTP
mysql数据库：
database: vsftpdvirtual
tables: users ##保存虚拟用户信息；用户名为zhouzhong
logs ##保存日志信息
PAM配置文件如下：
/etc/pam.d/vsftpd
....
auth required pam_mysql.so user=vsftpdvirtual passwd=123456 host=localhost db=vsftpdvirtualtable=users usercolumn=name passwdcolumn=passwdcrypt=0 sqllog=yes logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhostlogtimecolumn=logtimeverbose=1
account required pam_mysql.so user=vsftpdvirtual passwd=123456 host=localhost db=vsftpdvirtualtable=users usercolumn=name passwdcolumn=passwdcrypt=0 sqllog=yes logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhostlogtimecolumn=logtimeverbose=1
vsftpd.conf主配置文件如下：
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
xferlog_enable=YES
connect_from_port_20=YES
xferlog_std_format=YES
chroot_local_user=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list
listen=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
anon_upload_enable=YES
anon_mkdir_write_enable=YES
anon_other_write_enable=YES
listen_port=21
guest_enable=YES
guest_username=vsftpdvirtual
pasv_enable=YES
pasv_min_port=30000
pasv_max_port=30999
anon_world_readable_only=NO
virtual_use_local_privs=YES
user_config_dir=/etc/vsftpd/vsftpd_user_conf
以下是日志 /var/log/secure

Dec5 15:59:25 localhost vsftpd: pam_succeed_if(vsftpd:auth): error retrieving information about user zhouzhong 重新配置，重启；查了下日志；
发现其实可以往里面logs表里面写日志的；

但就是没法登陆

Dec5 16:47:03 localhost vsftpd: pam_succeed_if(vsftpd:auth): error retrieving information about user zhouzhong
虚拟用户、以及虚拟用户映射的本地用户，都无法登陆。
如果我开启了vsftpd.conf中匿名用户 anonymous_enable=YES，则可以匿名登录。
真是纠结啊
刚才又试了一下：如果把本地用户vsftpdvirtual，插入到 虚拟用户的user表中，就可以登录了； 打算把我的修改记录下来，希望我能调通，其他人别再碰到这种问题了！
还是不行！虚拟用户登录总是提示：
Dec5 20:55:30 localhost vsftpd: pam_unix(vsftpd:auth): check pass; user unknown
Dec5 20:55:30 localhost vsftpd: pam_unix(vsftpd:auth): authentication failure; logname= uid=0 euid=0 tty=ftp ruser=zhouzhong rhost=219.224.168.117
Dec5 20:55:30 localhost vsftpd: pam_succeed_if(vsftpd:auth): error retrieving information about user zhouzhong 终于找到原因了，还是pam文件的问题：重新写了一次；
1. /etc/pam.d/vsftpd原文件不变，再重新cp一份为vsftpd.mysql，并在该文件添加2行：auth、accout; 我之前一直是在原vsftpd文件上追加的，不知道是不是这个原因。
2 vsftpd.conf文件中， pam_service_name=vsftpd.mysql local_enable=YES 我也遇到同样问题,烦请贴一下完整的我参考. 回复 8# pklam
# cat /etc/pam.d/vsftpd.mysql
auth required /lib/security/pam_mysql.so user=**** passwd=****** host=localhost db=******* table=users usercolumn=name passwdcolumn=passwd crypt=0 sqllog=1 logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhost logtimecolumn=logtime verbose=1
account required /lib/security/pam_mysql.so user=***** passwd=******* host=localhost db=******* table=users usercolumn=name passwdcolumn=passwd crypt=0 sqllog=1 logtable=logs logmsgcolumn=msg logusercolumn=user logpidcolumn=pid loghostcolumn=host logrhostcolumn=rhost logtimecolumn=logtime verbose=1
是我机器现在的配置
我的也是同样故障，郁闷。
