要在Linux上使用Active Directory进行身份验证,你可以按照以下步骤进行操作:

  1. 创建一个新的ASP.NET Core 3.1项目:

    dotnet new webapp -n ADAuthExample
    cd ADAuthExample
    
  2. 添加所需的NuGet包:

    dotnet add package Microsoft.AspNetCore.Authentication.ActiveDirectory
    
  3. appsettings.json文件中添加必要的配置信息,包括Active Directory的域名、LDAP连接字符串以及要进行身份验证的用户组:

    {
      "ActiveDirectory": {
        "Domain": "your-domain.com",
        "LdapConnection": "ldap://your-domain.com",
        "UserGroup": "CN=YourGroupName,OU=YourOrganizationUnit,DC=your-domain,DC=com"
      },
      "Logging": {
        "LogLevel": {
          "Default": "Information",
          "Microsoft": "Warning",
          "Microsoft.Hosting.Lifetime": "Information"
        }
      }
    }
    
  4. Startup.cs文件中配置身份验证服务:

    using Microsoft.AspNetCore.Authentication.ActiveDirectory;
    
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(IISDefaults.AuthenticationScheme);
    }
    
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        app.UseAuthentication();
        app.UseAuthorization();
    }
    
  5. 创建一个自定义的身份验证处理程序,用于验证用户的身份和授权:

    using Microsoft.AspNetCore.Authentication;
    using Microsoft.AspNetCore.Authentication.ActiveDirectory;
    using Microsoft.Extensions.Configuration;
    using Microsoft.Extensions.Options;
    using System.Security.Claims;
    using System.Text.Encodings.Web;
    using System.Threading.Tasks;
    
    public class ActiveDirectoryAuthenticationHandler : AuthenticationHandler
    {
        private readonly IConfiguration _configuration;
    
        public ActiveDirectoryAuthenticationHandler(
            IOptionsMonitor options,
            ILoggerFactory logger,
            UrlEncoder encoder,
            ISystemClock clock,
            IConfiguration configuration)
            : base(options, logger, encoder, clock)
        {
            _configuration = configuration;
        }
    
        protected override async Task HandleAuthenticateAsync()
        {
            var domain = _configuration["ActiveDirectory:Domain"];
            var ldapConnection = _configuration["ActiveDirectory:LdapConnection"];
            var userGroup = _configuration["ActiveDirectory:UserGroup"];
    
            // 在此处编写身份验证逻辑,例如使用LDAP绑定验证
    
            var claims = new[]
            {
                new Claim(ClaimTypes.Name, "username"),
                new Claim(ClaimTypes.Email, "email@example.com"),
                // 添加其他所需的声明
            };
    
            var identity = new ClaimsIdentity(claims, Scheme.Name);
            var principal = new ClaimsPrincipal(identity);
            var ticket = new AuthenticationTicket(principal, Scheme.Name);
    
            return await Task.FromResult(AuthenticateResult.Success(ticket));
        }
    }
    
  6. Startup.cs文件中使用自定义的身份验证处理程序:

    using Microsoft.AspNetCore.Authentication.ActiveDirectory;
    
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = ActiveDirectoryAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = ActiveDirectoryAuthenticationDefaults.AuthenticationScheme;
        })
        .AddScheme(ActiveDirectoryAuthenticationDefaults.AuthenticationScheme, options =>
        {
            options.Domain = Configuration["ActiveDirectory:Domain"];
            options.LdapConnectionPath = Configuration["ActiveDirectory:LdapConnection"];
            options.UserGroup = Configuration["ActiveDirectory:UserGroup"];
        });
    }
    
  7. 在需要进行身份验证的控制器或操作方法中添加[Authorize]特性:

    [Authorize]
    public class HomeController : Controller
    {
        // ...
    }
    

现在你已经完成了在Linux上使用Active Directory进行身份验证的配置。在进行身份验证时,将使用自定义的身份验证处理程序来验证用户的身份和授权。你可以在HandleAuthenticateAsync方法中编写适合你的身份验证逻辑,例如使用LDAP绑定验证。根据验证结果,你可以创建一个包含所需声明的ClaimsIdentity对象,并使用它来创建AuthenticationTicket对象,然后返回AuthenticateResult.Success(ticket)
