问题描述

如何根据 Active Directory 验证用户名和密码?我只想检查用户名和密码是否正确.

How can I validate a username and password against Active Directory? I simply want to check if a username and password are correct.

推荐答案

如果您使用 .NET 3.5 或更高版本,您可以使用 System.DirectoryServices.AccountManagement 命名空间并轻松验证您的凭据:

If you work on .NET 3.5 or newer, you can use the System.DirectoryServices.AccountManagement namespace and easily verify your credentials:

// create a "principal context" - e.g. your domain (could be machine, too)
using(PrincipalContext pc = new PrincipalContext(ContextType.Domain, "YOURDOMAIN"))
{
    // validate the credentials
    bool isValid = pc.ValidateCredentials("myuser", "mypassword");
}

它很简单,很可靠,它是 100% 的 C# 托管代码——你还能要求什么?:-)

It's simple, it's reliable, it's 100% C# managed code on your end - what more can you ask for? :-)

其他 SO 问题(及其答案)中所述,此调用存在一个问题,可能为用户的旧密码返回 True.请注意这种行为,如果发生这种情况不要太惊讶:-)(感谢@MikeGledhill 指出这一点!)

As outlined in this other SO question (and its answers), there is an issue with this call possibly returning True for old passwords of a user. Just be aware of this behavior and don't be too surprised if this happens :-) (thanks to @MikeGledhill for pointing this out!)
