[英]LDAP Authentication with Asp.NET Identity
我尝试为我的ASP.NET MVC应用程序实现Active Directory身份验证。 我使用System.DirectoryServices并在登录期间在UserManager中查找用户。 如果用户未找到我正在尝试在Active Directory中查找用户,并且如果使用UserManager.CreateAsync()成功注册用户在asp.net mvc应用程序中。
private ApplicationUserManager _userManager;
private ApplicationRoleManager _roleManager;
//
// POST: /Account/Login
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel loginModel, string returnUrl)
{
if (ModelState.IsValid)
{
var user = await UserManager.FindAsync(loginModel.UserName, loginModel.Password);
if (user != null)
{
await SignInAsync(user, loginModel.RememberMe);
return RedirectToLocal(returnUrl);
}
string userFullName;
if (AuthenticateActiveDirectoryUser("mydomain.local", loginModel.UserName, loginModel.Password, out userFullName))
{
var newUser = new ApplicationUser { UserName = loginModel.UserName, FullName = userFullName };
var result = await UserManager.CreateAsync(newUser, loginModel.Password);
if (result.Succeeded)
{
await SignInAsync(newUser, loginModel.RememberMe);
return RedirectToLocal(returnUrl);
}
AddErrors(result);
}
else
{
ModelState.AddModelError("", "Invalid UserName or Password");
}
}
return View(loginModel);
}
private bool AuthenticateActiveDirectoryUser(
string domain,
string username,
string password,
out string fullName)
{
fullName = string.Empty;
var domainAndUsername = string.Format("{0}\\{1}", domain, username);
var ldapPath = "";
var entry = new DirectoryEntry(ldapPath, domainAndUsername, password);
try
{
// Bind to the native AdsObject to force authentication.
var obj = entry.NativeObject;
var search = new DirectorySearcher(entry) { Filter = "(SAMAccountName=" + username + ")" };
search.PropertiesToLoad.Add("cn");
var result = search.FindOne();
if (result == null)
return false;
try
{
fullName = (string)result.Properties["cn"][0];
}
catch
{
fullName = string.Empty;
}
}
catch (Exception ex)
{
return false;
}
return true;
}
但是在我的实现中忽略了用户更改Active Directory帐户或AD帐户中的密码的情况。 我可以在我的代码中手动检查它,但是在ASP.NET Identity中可能存在其他方式来实现Active Directory用户帐户的身份验证?
看看这是否可以帮助你
protected bool ActiveDirectoryLogin(string Username, string Password, string Domain)
{
bool Success = false;
//System.DirectoryServices.DirectoryEntry Entry =
// new System.DirectoryServices.DirectoryEntry("LDAP://***.**.**.**:389/cn=***-People,o=**,dc=**,dc=edu,dc=sa", "uid=" + Username + ",cn=***-People,o=***,dc=***,dc=edu,dc=sa", Password, AuthenticationTypes.None);
System.DirectoryServices.DirectoryEntry Entry =
new System.DirectoryServices.DirectoryEntry("LDAP://ldapmaster.***.edu.sa:389/cn=***-People,o=***,dc=***,dc=edu,dc=sa", "uid=" + Username + ",cn=***-People,o=***,dc=***,dc=edu,dc=sa", Password,AuthenticationTypes.None);
//System.DirectoryServices.DirectoryEntry Entry =
// new System.DirectoryServices.DirectoryEntry("LDAP://ldapmaster.***.edu.sa:389/cn=***-People,o=***,dc=***,dc=edu,dc=sa", Username , Password, AuthenticationTypes.None);
System.DirectoryServices.DirectorySearcher Searcher = new System.DirectoryServices.DirectorySearcher(Entry);
try
{
Object nat = Entry.NativeObject;
Success = true;
// System.DirectoryServices.SearchResult Results = Searcher.FindOne();
// Success = (Results != null);
}
catch (Exception e)
{
Success = false;
}
return Success;
}
