奇怪的passwd提示

interwenq

受伤有一台rhel5 , 我passwd后  为啥要我两次输入新密码？ 输出如下：

$ passwd
Changing password for user adm9.
Changing password for adm9
(current) UNIX password:
New UNIX password:
Retype new UNIX password:
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

好像跟pam有关，配置贴上：

这麽奇怪应该是有人改了pam

shell@debian:~$ cat /etc/pam.d/passwd
#
# The PAM configuration file for the Shadow `passwd' service

@include common-password
