给用户改密码出现的问题

try_jim

我的redhat9 上用
useradd test
passwd test
出现如下问题
User not known to the underlying authentication module
这是别人用过的linux服务器，好象认证模式不对，怎么修改，请高手赐教！

KornLee

切换到root,然后
passwd -d username
passwd username
这样试试看吧

try_jim

我就是用的root用户！

楼上的兄弟，不行啊！不过还谢谢你！

查看一下/etc/login.defs和/etc/pam.d/passwd文件

try_jim

etc/pam.d/passwd

/etc/login.defs
[root@localhost /]# vi /etc/login.defs
# *REQUIRED*
#   Directory where mailboxes reside, _or_ name of file, relative to the

没什么问题呀~~~,看看passwd和useradd文件有什么问题!
/home/lee#ll /usr/bin/passwd
-r-s--x--x    1 root     root        16336 2003-02-14  /usr/bin/passwd
/home/lee#ll /usr/sbin/useradd
-rwxr-xr-x    1 root     root        56088 2003-02-13  /usr/sbin/useradd

切换到root的时候,su后面要加上-号,即: su - root

try_jim

好象还不行，我要问问以前那个管理员！知道了我再发上来！
