pam_get_authtok_verify returned error: failed preliminary check by password 这个错误消息通常与 PAM(Pluggable Authentication Modules,可插拔认证模块)在 Linux 系统中的密码验证过程相关。以下是一些可能导致这个错误的原因以及相应的解决方法: 可能的原因及解决方法 密码
The implementation ofpam_sm_authenticate(3PAM)prompts the user name if not set and then tries to get the authentication token from the pam handle. If the token is not set, it then prompts the user for a password and stores it in thePAMitemPAM_AUTHTOK. This module is meant to be the...
The pam_unix(5) module might not be supported in a future release. Similar functionality is provided by pam_authtok_check(5), pam_authtok_get(5), pam_authtok_store(5), pam_dhkeys(5), pam_passwd_auth(5), pam_unix_account(5), pam_unix_auth(5), and pam_unix_session(5).Sun...
pam_chauthtok 子例程通过 PAM 框架更改用户的认证令牌。 在更改密码之前,子例程会执行初步测试,以确保存在必需的主机和信息 (取决于密码服务)。 如果其中任何测试失败,那么将返回 PAM_TRY_AGAIN。 要向用户请求信息, pam_chauthtok 可以使用 PAM 句柄 PAMHandle中定义的对话函数。 子例程完成后,将在句柄中清除...
