SUMMARY | 问题概要

UOS20 1060系统上编写自定义的pam模块，代码如下（只是一个样例）：

#include <security/pam_modules.h>
#include <security/pam_ext.h>
#include <string.h>

// PAM模块入口函数，实现用户认证功能
PAM_EXTERN int pam_sm_authenticate(pam_handle_t *pamh, int flags, int argc, const char **argv) {
const char *username = NULL;
const char *password = NULL;
int retval;

// 获取用户名和密码
retval = pam_get_user(pamh, &username, "Username: ");
if (retval != PAM_SUCCESS) {
    return retval;
}

retval = pam_get_authtok(pamh, PAM_AUTHTOK, &password, "Password: ");
if (retval != PAM_SUCCESS || password == NULL) {
    return retval;
}

// 进行身份验证
if (strcmp(username, "test") != 0 || strcmp(password, "123abc") != 0) {
    return PAM_AUTH_ERR;
}

return PAM_SUCCESS;
}

pam配置文件如下（/etc/pam.d/common-auth）： auth [success=done auth_err=die ignore=ignore default=bad] /usr/lib/security/libtest_pam.so

test@uos-PC:~$ ls /usr/lib/security/ libtest_pam.so pam_udcp.so
