[求助]:Selinux 安装poppassd,发现没有PAM_pwdb.so

andio

在redhat as5上安装了poppassd,在pam里做了设置,poppassd 的106端口也起来了
通过telnet这个端口来测试是否能够修改密码,始终发现出现:
200 poppassd v1.8.5 hello, who are you?
username test
200 Your password please.
password 123456
500 Old password is incorrect.

pam里的poppassd文件如下:
#%PAM-1.0
        auth       required     /lib/security/pam_pwdb.so shadow nullok
        account    required     /lib/security/pam_pwdb.so
        password   required     /lib/security/pam_cracklib.so retry=3
        password   required     /lib/security/pam_pwdb.so use_authtok nullok

但是检查/lib/security/pam_pwdb.so 该文件比不存在
不知道为什么,还请高手帮忙分析问题
不甚感激

使用telnet来测试
[root@localhost pam.d]# telnet 127.0.0.1 106
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
200 poppassd v1.8.1 hello, who are you?
username test
200 Your password please.
password 123456
500 Old password is incorrect.
Connection closed by foreign host.

明明密码是对的,就是认不出来,还请高手帮我分析下,谢谢
