我要评论使用c#对网域账号(domain)验证方案:
一、使用advapi32.dll动态库
[dllimport("advapi32.dll")]
private static extern bool logonuser(string lpszusername, string lpszdomain, string lpszpassword, int dwlogontype, int dwlogonprovider, ref intptr phtoken);
const int logon32_logon_interactive = 2; //通过网络验证账户合法性
const int logon32_provider_default = 0; //使用默认的windows 2000/nt ntlm验证方
public static bool checkadaccount(string account, string password)
{
intptr tokenhandle = new intptr(0);
tokenhandle = intptr.zero;
string domainname = "dpbg";
if (logonuser(account, domainname, password, logon32_logon_interactive, logon32_provider_default, ref tokenhandle))
return true;
return false;
}注意使用该动态库可能会导致 服务local security authority process 内存异常升高且无法回收现象
二、使用 system.directoryservices
/// <summary>
/// 验证网域账号
/// </summary>
/// <param name="account">账号</param>
/// <param name="password">密码</param>
/// <param name="domain">网域</param>
/// <param name="name">姓名</param>
/// <returns></returns>
public static bool checkadaccountnew(string account, string password, string domain, out string name)
{
name = "";
using (directoryentry deuser = new directoryentry(@"ldap://" + domain, account, password))
{
directorysearcher src = new directorysearcher(deuser);
src.filter = "(&(&(objectcategory=person)(objectclass=user))(samaccountname=" + account + "))";
src.propertiestoload.add("cn");
src.searchroot = deuser;
src.searchscope = searchscope.subtree;
try
{
searchresult result = src.findone();
if (result != null)//验证成功
{
if (result.properties["cn"] != null)//依据实际属性获取用户信息
{
name = result.properties["cn"][0].tostring();
}
return true;
}
return false;
}
catch
{
return false;
}
}
}注意如果域内账号较多时,验证不存在的账号速度较慢且不会验证密码的有效期
三、使用system.directoryservices.accountmanagement
/// <summary>
/// 验证网域账号
/// </summary>
/// <param name="account">账号</param>
/// <param name="password">密码</param>
/// <param name="domain">网域</param>
/// <param name="name">姓名</param>
/// <returns></returns>
public static bool checkadaccountnew(string account, string password, string domain, out string name)
{
name = "";
using (var domaincontext = new principalcontext(contexttype.domain, domain))
{
using (var founduser = userprincipal.findbyidentity(domaincontext, identitytype.samaccountname, account))
{
if (founduser == null)
{
return false;
}
name = founduser.name;
if (domaincontext.validatecredentials(account, password))
{
return true;
}
else
{
return false;
}
}
}
}注意该方法不会验证密码的有效期
