Linux 登陆认证
PAM: pluggable authentication modules for linux
http://www.linux-pam.org/whatispam.html
A suite of shared libraries that enable the local system administrator to choose how applications authenticate users.
/etc/pam.conf
(or a series of configuration files located in /etc/pam.d/
)
/lib/security
or /lib64/security
一般Unix系统就是终端输入用户名和密码,到/etc/passwd中认证下,linux 中这种方法delicated了
PAM主要是配置管理4个方面:
authentication management;
account management;
session management;
password management
