passwd: Authentication token manipulation error


解决办法

检查/etc/pam.d/passwd、/etc/pam.d/system-auth以下配置是否存在:


1、cat /etc/pam.d/passwd

#%PAM-1.0

auth    required   pam_stack.so service=system-auth

account  required   pam_stack.so service=system-auth

password  required   pam_stack.so service=system-auth


password required pam_cracklib.so dcredit=-1 ucredit=-1 ocredit=-1 lcredit=-1 minlen=6

password required pam_unix.so use_authtok nullok md5

password required pam_unix.so remember=5 use_authtok

最后这三行有些老系统不支持,设置后也会导致上面的报错


2、cat /etc/pam.d/system-auth

#%PAM-1.0

# This file is auto-generated.

# User changes will be destroyed the next time authconfig is run.

auth    required   /lib/security/$ISA/pam_env.so

auth    sufficient  /lib/security/$ISA/pam_unix.so likeauth nullok

auth    required   /lib/security/$ISA/pam_deny.so


account   required   /lib/security/$ISA/pam_unix.so

account   sufficient  /lib/security/$ISA/pam_succeed_if.so uid < 100 quiet

account   required   /lib/security/$ISA/pam_permit.so


password  requisite   /lib/security/$ISA/pam_cracklib.so retry=3

password  sufficient  /lib/security/$ISA/pam_unix.so nullok use_authtok md5 shadow

password  required   /lib/security/$ISA/pam_deny.so


session   required   /lib/security/$ISA/pam_limits.so

session   required   /lib/security/$ISA/pam_unix.so



3、也可以直接修改shadow文件密码串

方法一)

perl -e 'print crypt("password","\$1\$2BDxrkQc\$"),"\n"'

注:这里的2BDxrkQc,是shadow中salt($3)的内容,如果要随机生成salt,可使用方法二。


方法二)

echo "password" | openssl passwd -1 -salt $(< /dev/urandom tr -dc '[:alnum:]' | head -c 32) -stdin
