活动目录findone()方法

Question

我试图通过使用这条线来询问广告

            DirectoryEntry de = null;
            SearchResult results = null;
            de = new DirectoryEntry();

            //geting the result FROM ad
            de.Path = dr.manager;
            de.AuthenticationType = AuthenticationTypes.Secure;
            DirectorySearcher search = new DirectorySearcher(de);
            search.Filter = string.Format("(objectClass={0})",'*');
            search.PropertiesToLoad.Add("IsraelID");
            results = search.FindOne();
            de = results.GetDirectoryEntry();

但我在findone()中得到一个例外

System.Runtime.InteropServices.COMException (0x80004005): Unspecified error

   at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)
   at System.DirectoryServices.DirectoryEntry.Bind()
   at System.DirectoryServices.DirectoryEntry.get_AdsObject()
   at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne)
   at System.DirectoryServices.DirectorySearcher.FindOne()

未指定的错误意味着您的LDAP路径缺少LDAP协议标识符.确保您的路径包含大写的LDAP协议标识符.

例:

DirectoryEntry de = null; 
SearchResult results = null; 
de = new DirectoryEntry(); 

// Assuming your domain dns name is treyresearch.net 
de.Path = "LDAP://servername/CN=users,DC=treyresearch,DC=net"; 
de.AuthenticationType = AuthenticationTypes.Secure; 
de.Username = "treyresearch\\Administrator";
de.Password = "P@$$W0rd";
DirectorySearcher search = new DirectorySearcher(de); 
search.Filter = string.Format("(objectClass={0})",'*'); 
search.PropertiesToLoad.Add("IsraelID"); 
results = search.FindOne(); 
de = results.GetDirectoryEntry(); 

希望这可以帮助.
