在 RHEL 7.9 中，我passwd -S对所有帐户执行此操作/etc/passwd作为检查用户帐户的一部分。
# passwd -S <account name>

这是从 DVD 中全新安装的 RHEL 7.9 x86-64。以上是passwd -S对所有帐户执行的摘录/etc/passwd。有人可以告诉我什么意思以及对这些帐户执行某种命令（如果是的话是什么）(Alternate authentication scheme in use.)是否谨慎？passwdchage
基本上我预计在审计期间告诉我如何保护和管理用户帐户问题所以我解释一下我对 /etc/passwd 中的所有帐户执行 passwd -S但我该如何解释正在使用的替代身份验证方案？
fwiw，我正在chage -m 1 -M 90 -W 14 -I 5所有常规用户帐户上执行此操作。
