sufficient：表示该行以及所涉及模块验证成功是用户通过鉴别的充分条件。也就是说只要标记为sufficient的模块一旦验证成功，那么PAM便立即向应用程序返回成功结果而不必尝试任何其他模块。...当标记为sufficient的模块失败时，sufficient模块会当做 optional对待。...因此拥有sufficient 标志位的配置项在执行验证出错的时候并不会导致整个验证失败，但执行验证成功之时则大门敞开。所以该控制位的使用务必慎重。...pam_localuser.so account sufficient pam_succeed_if.so uid < 500 quiet account required...然后通过pam_unix.so模块来提示用户输入密码，并将用户密码与/etc/shadow中记录的密码信息进行对比，如果密码比对结果正确则允许用户登录，而且该配置项的使用的是“sufficient”控制位
