当我尝试获取用户所属的组时,出现“登录失败:未知用户名或密码错误”错误。用户身份验证正常工作,这是我无法理解的。我如何正确认证用户对AD的身份,但无法获得他的组名? 我得到用户的ID和密码。我有一个处理认证的类。LDAP获取组名称
if ((true == adAuth.IsAuthenticated(sDomain, sID, sPassword)))
{
string sGroups = adAuth.GetGroups();
这是认证类:
public class LdapAuthentication
{
string _path;
string _filterAttribute;
public LdapAuthentication(string path)
{
_path = path;
}
public bool IsAuthenticated(string domain, string username, string pwd)
{
string domainAndUsername = domain + "\\" + username;
DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, pwd);
try {
//Bind to the native AdsObject to force authentication.
object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";
search.PropertiesToLoad.Add("cn");
SearchResult result = search.FindOne();
if ((result == null)) {
return false;
}
//Update the new path to the user in the directory.
_path = result.Path;
_filterAttribute = Convert.ToString(result.Properties["cn"][0]);
}
catch (Exception ex) {
throw new Exception("Error authenticating user. " + ex.Message);
//return false;
}
return true;
}
public string GetGroups()
{
//DirectorySearcher search = new DirectorySearcher(_path);
// Use following two lines instead of the above to handle cases of authenticatin against an LDAP server other than local AD domain
DirectoryEntry deSearchRoot = new DirectoryEntry(_path);
DirectorySearcher search = new DirectorySearcher(deSearchRoot);
search.Filter = "(cn=" + _filterAttribute + ")";
search.PropertiesToLoad.Add("memberOf");
StringBuilder groupNames = new StringBuilder();
try {
SearchResult result = search.FindOne();
int propertyCount = result.Properties["memberOf"].Count;
string dn = null;
int equalsIndex = 0;
int commaIndex = 0;
int propertyCounter = 0;
for (propertyCounter = 0; propertyCounter <= propertyCount - 1; propertyCounter++) {
dn = Convert.ToString(result.Properties["memberOf"][propertyCounter]);
equalsIndex = dn.IndexOf("=", 1);
commaIndex = dn.IndexOf(",", 1);
if ((equalsIndex == -1)) {
return null;
}
groupNames.Append(dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex) - 1));
groupNames.Append("|");
}
} catch (Exception ex) {
throw new Exception("Error obtaining group names. " + ex.Message);
}
return groupNames.ToString();
}
IsAuthnticated的推移和工作正常; GetGroups()返回“错误获取组名称”,然后返回“登录失败:未知用户名或错误密码”(即GetGroups()中的异常)。
它运行良好,当我从VS运行应用程序,但当我发布它(在同一台服务器上),它的行为就像这样。 任何想法非常感谢。
