无法连接到 VPN 服务器 - 身份验证失败,错误代码 691

sta*_*ker 6 vpn authentication rras windows-server-2008-r2 nps

尝试连接到 VPN 服务器时,我在客户端上收到 691 错误代码,其中说:

错误描述:691:远程连接被拒绝,因为您提供的用户名和密码组合未被识别,或者远程访问服务器上不允许选择的身份验证协议。

我验证了用户名和密码是正确的。我还安装了与IKEv2安全类型一起使用的认证。我还验证了 VPN 服务器支持安全方法。

但我无法登录。在服务器日志中,我得到了这个日志:

网络策略服务器拒绝访问用户。

用户 DomainName\UserName 从 IP 地址连接,但由于以下原因导致身份验证尝试失败:远程连接被拒绝,因为您提供的用户名和密码组合未被识别,或者远程访问不允许选择的身份验证协议服务器。

知道我能做什么吗?提前致谢!

原因:由于用户凭据不匹配,身份验证失败。提供的用户名未映射到现有用户帐户或密码不正确。

我认为这就是你的问题所在。验证该帐户是否具有通过 RRAS 进行远程连接的正确权限。这些链接可能对您有帮助。请注意,适用于 2003 年的文章可能仍适用于 2008r2(根据 MSFT)。另请注意,我并不声称自己是主题专家......
