在 .NET MVC 中使用 LDAP/网络凭据验证用户 [英] Validate User With LDAP/Network Credential in .NET MVC

问题描述

我正在开发 .NET 中的 MVC 3 应用程序，我对 LDAP 没有太多经验，但我希望能够简单地验证用户是否存在.我不需要像本例中那样验证用户名和密码组合:

I'm working on an MVC 3 app in .NET, I don't have much experience with LDAP, but I wanted to be able to simply validate if a user exists. I don't need to validate the username and password combo as in this example:

ASP.Net MVC 中的 LDAP 身份验证

虽然这几乎是我想做的.我只需要在添加他/她之前验证用户名.

Although this is almost what I want to do. I just need to validate the username before he/she is added.

在 .NET/MVC 中是否有一种简单的方法来做到这一点

Is there a simple way to do this in .NET/MVC

推荐答案

使用 System.DirectoryServices.AccountManagement 命名空间并通过更改IdentityType 枚举.

Use the System.DirectoryServices.AccountManagement namespace and pass in the username or distinguished name (e.g. CN=John Doe) by altering the IdentityType enum.

public bool UserExists(string username) 
{ 
   PrincipalContext domain = new PrincipalContext(ContextType.Domain); 

   // locate the user
   UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.Name, username); 

   return user != null; 
}
