notsupportedException by active directory 2010-03-17 16:22 600人阅读 评论(2) 收藏

first, thx starfish's support, who offered the code below ;)

 

the package used by AD is System.DirectoryService;

DirectoryEntry is a leaf, and DirectoryEntries a collection of entries.

 

DirectoryEntry   oDE = new DirectoryEntry(_path, _userName, _password, AuthenticationTypes.Secure)

 

 

some words to path:

I wanted to modify or query some email adress from certain user. Because the users are scattered around the directories, so I can't use the usual CN=.. OU=.. stuff. so I did a query, found out the DirectoryEntry and then create a new Directory entry by the path element. with this methode I can get DN(distinguish name) of almost all elements. string user = "XX"; string pwd = "xxx"; DirectoryEntry root ; DirectoryEntry de = GetDirectoryObject("LDAP://itcenter.xxx.com.cn/rootDSE", user, pwd); try { root = de.Parent; object o = de.NativeObject; Console.Write("Succeed."); } catch (Exception ex) { Console.Write(ex.Message); return; } DirectorySearcher deSearch = new DirectorySearcher(); deSearch.SearchRoot = root; deSearch.Filter = "(&(objectClass=user)(sAMAccountName=" + user + "))"; deSearch.SearchScope = SearchScope.Subtree; SearchResult results = deSearch.FindOne(); if (!(results == null)) { de = new DirectoryEntry(results.Path, user, pwd, AuthenticationTypes.Secure); } Console.Write(de.Properties["givenName"].Value); } public static DirectoryEntry GetDirectoryObject(string _path, string _userName, string _password) { DirectoryEntry oDE; oDE = new DirectoryEntry(_path, _userName, _password, AuthenticationTypes.Secure); return oDE; } }  

to be noticed is, that rootDSE ist not the real root, but rootDSE.Parent, if you do some query with rootDSE, you will get a notsupportedException, search not supported, don't think the admi has turned search off. rootDSE is a leaf! only container types supports search( it makes no sense by search elments in a single element). The rest is straight ahead and self explaining. (the code is based on the help source code  of starfish, thx a lot ;)))
