用echo username:passwd | chpasswd可以修改

应该还是PAM配置的问题，检查一下你的password include        common-password中common-password 模块的说明，或者先去掉pam.d/password

我把common-password注释掉ok了，看了下common-password模块，目的是对密码规则做个限制，看来问题出在了这
这个common-password有什么问题呢？能这样配置吗？
#password required       pam_pwcheck.so nullok
#password required       pam_unix2.so    nullok use_first_pass use_authtok
#password required      pam_make.so     /var/yp
password  requisite     pam_passwdqc.so ask_oldauthtok=update check_oldauthtok min=disabled,disabled,disabled,disabled,6 min_digits=1 min_chars=3 min_uppers=1 min_lowers=1 min_others=1 passphrase=0
password  requisite     pam_pwcheck.so use_first_pass use_authtok
password  required      pam_unix2.so use_first_pass use_authtok

pam的各个验证模块都有自己的定义说明，我对你使用的pwcheck,passwdqc不熟悉，一般我只使用unix2.so

回复 #4 bwater 的帖子

min_lowers=1

应该是这个问题。

你密码中是否包含了至少一个小写字母啊？
