我坚持在CentOS 7中使用两个因子认证来工作;特别是通过SSH和OTP进行身份验证 .

如果有人可以帮助我，我将非常感激 . :)

以下是尝试使用帐户“ws-admin@test.local”通过SSH登录的日志：

sshd[3652]: pam_radius_auth: Got user name ws-admin@test.local

Below follow Configuration- and Setup-Infos

测试环境由我公司的基础设施提供;我们主要使用Windows客户端和Windows和Linux服务器的相同份额 .

Win-Server ：Windows Server 2016 x64

  • Active Directory：Test.local

  • ESET安全认证（ RADIUS Server ）

  • 与客户共享秘密：test345

  • 选项"Use Access-Challenge feature of RADIUS"已启用

Linux-Client/Server ：CentOS 7 x64

  • 通过 realm 加入Domain Test.local

  • 随时可以使用AD-Accounts和OTP-2FA进行本地登录

  • 只有 /etc/pam.d/sshd 未在 /etc/pam.d/sshd 中设置 required （这意味着没有2FA），才可以使用任何帐户登录

Linux-Client / Server的 Configuration ：

  • 在 /etc/raddb/server 中添加了RADIUS-Server和Shared-Secret

  • pam_radius_auth.so 在 /usr/lib64/security/

  • auth required pam_radius_auth.so 已添加至 /etc/pam.d/sshd 和 /etc/pam.d/login

/etc/pam.d/login
