我在Windows Vista Ultimate SP1上使用以下代码查询我们的活动目录服务器,以检查域中用户的用户名和密码。
public Object IsAuthenticated()
{
String domainAndUsername = strDomain + "\\" + strUser;
DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, strPass);
SearchResult result;
try
{
//Bind to the native AdsObject to force authentication.
DirectorySearcher search = new DirectorySearcher(entry) { Filter = ("(SAMAccountName=" + strUser + ")") };
search.PropertiesToLoad.Add("givenName"); // First Name
search.PropertiesToLoad.Add("sn"); // Last Name
search.PropertiesToLoad.Add("cn"); // Last Name
result = search.FindOne();
if (null == result)
{
return null;
}
//Update the new path to the user in the directory.
_path = result.Path;
_filterAttribute = (String)result.Properties["cn"][0];
}
catch (Exception ex)
{
return new Exception("Error authenticating user. " + ex.Message);
}
return user;
}
目标使用的是.NET 3.5,并且是使用VS 2008标准版编译的。
我以应用程序运行的域帐户登录,该帐户是域管理员。
代码在Windows XP上完美运行;但是在Vista上运行时出现以下异常:
System.DirectoryServices.DirectoryServicesCOMException (0x8007052E): Logon failure: unknown user name or bad password.

我已经尝试更改认证类型,但不确定出了什么问题。
