各位达人：

小弟昨天遇到了一个奇怪的问题，当使用.net获取域信息时，在VS中运行可以正常读取域及域用户信息，但是当网站发布后，就无法获取域信息。

private staticDirectoryEntry GetDirectoryObject()

        {      

DirectoryEntry entry = newDirectoryEntry("LDAP://EMRSN", "adm", "Fengye", AuthenticationTypes.Secure);

return entry;

        }

publicstaticDirectoryEntry GetDirectoryEntryByAccount(string sAMAccountName)

        {

DirectoryEntry de = GetDirectoryObject();

DirectorySearcher deSearch = newDirectorySearcher(de);

            deSearch.Filter =

"(&(&(objectCategory=person)(objectClass=user))(sAMAccountName=" + sAMAccountName + "))";

            deSearch.SearchScope =

SearchScope.Subtree;

try

            {

SearchResult result = deSearch.FindOne();

                de =

newDirectoryEntry(result.Path);

return de;

            }

catch

            {

returnnull;

            }

        }

publicstring getUsername()

{

string username = System.Security.Principal.WindowsIdentity.GetCurrent().Name;

string[] info = username.Split(newchar[1] { '\\' }, StringSplitOptions.RemoveEmptyEntries);

string adname="";

if (Environment.UserDomainName.Equals("EMRSN"))

            {

DirectoryEntry de = newDirectoryEntry();

                de = GetDirectoryEntryByAccount(info[1]);

if (de != null)

                {

if (de.Properties["distinguishedName"][0].ToString().Contains("Xian-eResource"))

                   {

                      adname= de.Properties["displayname"][0].ToString();

                   }

else

                   {

                      adname="";

                   }

                 }

else

                 {

                     adname="";

                 }   

}

return adname;

}

高手解救啊，谢谢！
