如何在C#中获取登录用户的OU？

我正在寻找一种方法来获取当前登录用户的完整Active Directory LDAP路径。e、 g

LDAP://CN=john.smith,OU=UK,OU=Sales,DC=Company,DC=local

使用此筛选器查询LDAP目录（例如AD）：

(&(objectCategory=user)(sAMAccountName=<user-logon-name-here>))

DirectorySearcher ds = new DirectorySearcher();
string userName = WindowsIdentity.GetCurrent().Name;
string userFilter = "(&(objectCategory=user)(sAMAccountName={0}))";

ds.SearchScope = SearchScope.Subtree;
ds.PropertiesToLoad.Add("distinguishedName");
ds.PageSize = 1;
ds.ServerPageTimeLimit = TimeSpan.FromSeconds(2);
ds.Filter = string.Format(userFilter, userName);

SearchResult sr = ds.FindOne();
// now do something with sr.Properties["distinguishedName"][0]
