  To integrate LDAP (Active Directory) authentication in an ABP MVC Core Razor application, follow these steps:

  1. Install the necessary NuGet package:

     • Add the Volo.Abp.Account.Pro.Ldap package to your project.

  2. Configure LDAP settings in your appsettings.json:

  "Ldap": {
       "IsEnabled": "true",
       "Domain": "your-domain",
       "UserName": "ldap-user",
       "Password": "ldap-password",
       "ServerHost": "your-ldap-server",
       "ServerPort": "389"
     }
  

  3. Enable the LDAP login feature:

     • Go to the Feature Management UI in your application.
     • Enable the Account.EnableLdapLogin feature for the relevant tenant or host.

  4. Test your LDAP configuration:

     • You can use the provided ABP LDAP Test Application to verify your LDAP settings before integrating them into your main application.
     • Repository: https://github.com/abpframework/abp-samples/tree/master/AbpLdapSample

  5. Clear the cache if you change feature settings to ensure the new configuration is applied.

  After these steps, users will be able to log in using their Active Directory credentials.

  public async static Task<int> Main(string[] args)
  {
      var server = "xxx.xxx.com";
      var serverPort = 12345;
      var baseDc = "DC=xxx,DC=com";
      var adminUserName = "xxx";
      var adminPassword = "xxx";
      var testUserName = "xxx@xxx.com"; // Replace with a real AD user
      var testPassword = "xxx";         // Replace with actual password
  
      using (var ldapConnection = new LdapConnection())
      {
          ldapConnection.Connect(server, serverPort, Native.LdapSchema.LDAP, Native.LdapVersion.LDAP_VERSION3);
  
          try
          {
              // Bind as LDAP admin (Bind DN)
              await ldapConnection.BindAsync(Native.LdapAuthType.Simple, new LdapCredential
              {
                  UserName = $"CN={adminUserName},{baseDc}",  // Important: Full DN of bind user
                  Password = adminPassword
              });
  
              Console.WriteLine($"{adminUserName} bind success!");
  
              // Search for the user using sAMAccountName (common in Active Directory)
              var filter = $"(&(objectClass=user)(sAMAccountName={testUserName}))";
              var searchResults = await ldapConnection.SearchAsync(baseDc, filter);
  
              if (!searchResults.Any())
              {
                  Console.WriteLine($"User {testUserName} not found.");
                  
              }
  
              var userEntry = searchResults.First();
              Console.WriteLine();
              Console.WriteLine($"{testUserName} attributes:");
              Console.WriteLine(string.Join(", ", userEntry.ToDirectoryEntry().Attributes));
  
              // Now bind as the found user to test password
              await ldapConnection.BindAsync(Native.LdapAuthType.Simple, new LdapCredential
              {
                  UserName = userEntry.Dn,
                  Password = testPassword
              });
  
              Console.WriteLine();
              Console.WriteLine($"{testUserName} login success!");
          }
          catch (Exception e)
          {
              Console.WriteLine("LDAP Error:");

  hi

  I don't know about your LDAP server, you can try to replace several filter strings

  var filter = $"(&(objectClass=user)(sAMAccountName={testUserName}))";

  Thanks.

  I don't know about your LDAP server, you can try to replace several filter strings.

  var filter = $"(&(objectClass=user)(sAMAccountName={testUserName}))";

  Thanks,

   var filter = $"(&(objectClass=person)(uid={testUserName}))"; this works for me when try this 
  
  var server = "xxxx";
  var serverPort = xxxx;
  var baseDc = "xxxx";
  
  var adminUserName = "xxxx";
  var adminPassword = xxxx";
  
  var testUserName = "xxxxx"; // short name or sAMAccountName
  var testPassword = "xxxx"; // real user password
  
  using (var ldapConnection = new LdapConnection())
  {
      ldapConnection.Connect(server, serverPort, Native.LdapSchema.LDAP, Native.LdapVersion.LDAP_VERSION3);
  
      try
      {
          // Bind as admin
          await ldapConnection.BindAsync(Native.LdapAuthType.Simple, new LdapCredential
          {
              UserName = $"CN={adminUserName},{baseDc}",
              Password = adminPassword
          });
  
          Console.WriteLine($"{adminUserName} login success!");
  
          // Search user
          var filter = $"(&(objectClass=person)(uid={testUserName}))";
          var searchResults = await ldapConnection.SearchAsync(baseDc, filter);
  
          var userEntry = searchResults.FirstOrDefault();
          if (userEntry == null)
          {
              Console.WriteLine($"User '{testUserName}' not found.");
           
          }
  
          Console.WriteLine($"{testUserName} DN: {userEntry.Dn}");
  
          // Try binding as the user
          await ldapConnection.BindAsync(Native.LdapAuthType.Simple, new LdapCredential
          {
              UserName = userEntry.Dn,
              Password = testPassword
          });
  
          Console.WriteLine($"{testUserName} login success!");
      }
      catch (Exception e)
      {
          Console.WriteLine($"LDAP Error: {e.Message}");
      }
  
      Console.ReadKey();
  }

  hi

  If your Program code works. You can replace the built-in code.

  https://abp.io/docs/latest/modules/identity/idap#customize-built-in-services

  There is no Volo.Abp.Account.Pro.Ldap package.

  The OpenLdapManager exists in Volo.Abp.Identity.Pro.Domain, It overrides some methods from LdapManager

  You don't need to add any extra packages, the default template already includes LDAP features.

  Thanks.
