的交互 一、Authentication Service Exchange KRB_AS_REQ(请求) Client --> AS:客户端向KDC的AS发送Authenticator1,内容包含: Pre-authentication 根据用户名在AD中判断是否在白名单中,接着进行验证发送方是否为Client name中声称的用户 也就是需要验证发送方是否知道该用户名的密码,此时只需要从AD中使用相应的NTLM Hash对请求包中的Pre-authentication
Cannot provide pre-authentication and SSO functionality , especially important for Exchange OWA and Sharepoint
NTLM over LDAP 暴力破解 Kerberos pre-authentication bruteforce:这是最快和最隐蔽的方式。 可以选择传输协议:UDP 或 TCP。
KRB_AS_REQ的大体包含以下的内容: Pre-authentication data:包含用以证明自己身份的信息。说白了,就是证明自己知道自己声称的那个account的Password。 所以AS只需从Account Database中提取Client对应的Master Key对Pre-authentication data进行解密,如果是一个合法的Timestamp,则可以证明发送放提供的是正确无误的密码

kerberos规范本身使用Pre-Authentication标头在TGS-REQ步骤中传递身份验证数据。kerberos预认证主要是防止用户密码爆破。
