如何对活动目录验证用户名和密码?我只是想检查用户名和密码是否正确。

这里是我完整的认证解决方案,供您参考。
首先,添加以下四个引用
using System.DirectoryServices;
using System.DirectoryServices.Protocols;
using System.DirectoryServices.AccountManagement;
using System.Net;
private void AuthUser() {
try{
string Uid = "USER_NAME";
string Pass = "PASSWORD";
if (Uid == "")
{
MessageBox.Show("Username cannot be null");
}
else if (Pass == "")
{
MessageBox.Show("Password cannot be null");
}
else
{
LdapConnection connection = new LdapConnection("YOUR DOMAIN");
NetworkCredential credential = new NetworkCredential(Uid, Pass);
connection.Credential = credential;
connection.Bind();
// after authenticate Loading user details to data table
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, Uid);
DirectoryEntry up_User = (DirectoryEntry)user.GetUnderlyingObject();
DirectorySearcher deSearch = new DirectorySearcher(up_User);
SearchResultCollection results = deSearch.FindAll();
ResultPropertyCollection rpc = results[0].Properties;
DataTable dt = new DataTable();
DataRow toInsert = dt.NewRow();
dt.Rows.InsertAt(toInsert, 0);
foreach (string rp in rpc.PropertyNames)
{
if (rpc[rp][0].ToString() != "System.Byte[]")
{
dt.Columns.Add(rp.ToString(), typeof(System.String));
foreach (DataRow row in dt.Rows)
{
row[rp.ToString()] = rpc[rp][0].ToString();
}
}
}
//You can load data to grid view and see for reference only
dataGridView1.DataSource = dt;
}
} //Error Handling part
catch (LdapException lexc)
{
String error = lexc.ServerErrorMessage;
string pp = error.Substring(76, 4);
string ppp = pp.Trim();
if ("52e" == ppp)
{
MessageBox.Show("Invalid Username or password, contact ADA Team");
}
if ("775" == ppp)
{
MessageBox.Show("User account locked, contact ADA Team");
}
if ("525" == ppp)
{
MessageBox.Show("User not found, contact ADA Team");
}
if ("530" == ppp)
{
MessageBox.Show("Not permitted to logon at this time, contact ADA Team");
}
if ("531" == ppp)
{
MessageBox.Show("Not permitted to logon at this workstation, contact ADA Team");
}
if ("532" == ppp)
{
MessageBox.Show("Password expired, contact ADA Team");
}
if ("533" == ppp)
{
MessageBox.Show("Account disabled, contact ADA Team");
}
if ("533" == ppp)
{
MessageBox.Show("Account disabled, contact ADA Team");
}
} //common error handling
catch (Exception exc)
{
MessageBox.Show("Invalid Username or password, contact ADA Team");
}
finally {
tbUID.Text = "";
tbPass.Text = "";
}
}

我们在内部网做这些
你必须使用System.DirectoryServices;
下面是代码的核心部分
using (DirectoryEntry adsEntry = new DirectoryEntry(path, strAccountId, strPassword))
{
using (DirectorySearcher adsSearcher = new DirectorySearcher(adsEntry))
{
//adsSearcher.Filter = "(&(objectClass=user)(objectCategory=person))";
adsSearcher.Filter = "(sAMAccountName=" + strAccountId + ")";
try
{
SearchResult adsSearchResult = adsSearcher.FindOne();
bSucceeded = true;
strAuthenticatedBy = "Active Directory";
strError = "User has been authenticated by Active Directory.";
}
catch (Exception ex)
{
// Failed to authenticate. Most likely it is caused by unknown user
// id or bad strPassword.
strError = ex.Message;
}
finally
{
adsEntry.Close();
}
}
}
可能最简单的方法是PInvoke LogonUser Win32 api。
http://www.pinvoke.net/default.aspx/advapi32/LogonUser.html
MSDN参考在这里…
http://msdn.microsoft.com/en-us/library/aa378184.aspx
绝对要使用登录类型
LOGON32_LOGON_NETWORK (3)
这只创建了一个轻量级的令牌-完美的认证检查。(其他类型可用于构建交互式会话等)
对我来说,这两个下面的工作,确保你的域名是LDAP://在开始
//"LDAP://" + domainName
private void btnValidate_Click(object sender, RoutedEventArgs e)
{
try
{
DirectoryEntry de = new DirectoryEntry(txtDomainName.Text, txtUsername.Text, txtPassword.Text);
DirectorySearcher dsearch = new DirectorySearcher(de);
SearchResult results = null;
results = dsearch.FindOne();
MessageBox.Show("Validation Success.");
}
catch (LdapException ex)
{
MessageBox.Show($"Validation Failure. {ex.GetBaseException().Message}");
}
catch (Exception ex)
{
MessageBox.Show($"Validation Failure. {ex.GetBaseException().Message}");
}
}
private void btnValidate2_Click(object sender, RoutedEventArgs e)
{
try
{
LdapConnection lcon = new LdapConnection(new LdapDirectoryIdentifier((string)null, false, false));
NetworkCredential nc = new NetworkCredential(txtUsername.Text,
txtPassword.Text, txtDomainName.Text);
lcon.Credential = nc;
lcon.AuthType = AuthType.Negotiate;
lcon.Bind(nc);
MessageBox.Show("Validation Success.");
}
catch (LdapException ex)
{
MessageBox.Show($"Validation Failure. {ex.GetBaseException().Message}");
}
catch (Exception ex)
{
MessageBox.Show($"Validation Failure. {ex.GetBaseException().Message}");
}
}
我使用这个过程作为DLL登录到我们开发的其他应用程序… (我们目前正在使用OpenEdge Progress)
public static string AzureLogin(string user, string password) {
string status;
try {
new DirectorySearcher(new DirectoryEntry("LDAP://yourdomain.com", user, password) {
AuthenticationType = AuthenticationTypes.Secure,
Username = user,
Password = password
}) {
Filter = "(objectclass=user)"
}.FindOne().Properties["displayname"][0].ToString();
status = $"SUCCESS - User {user} has logged in.";
} catch(System.Exception e) {
status = $"ERROR - While logging in: {e}";
}
return status;
}
我的简单功能
private bool IsValidActiveDirectoryUser(string activeDirectoryServerDomain, string username, string password)
{
try
{
DirectoryEntry de = new DirectoryEntry("LDAP://" + activeDirectoryServerDomain, username + "@" + activeDirectoryServerDomain, password, AuthenticationTypes.Secure);
DirectorySearcher ds = new DirectorySearcher(de);
ds.FindOne();
return true;
}
catch //(Exception ex)
{
return false;
}
}
