据我了解,这样做的一种方法是:
- 从 RootDSE 中,查找配置 NamingContext。
- 在配置 NamingContext 中寻找具有现有
crossRef
属性的类对象。nETBIOSName
- 从这些条目中,使用您通过 using
dnsRoot
和nCName
attributs 描述的算法。工作林 DNS 允许您加入dnsRoot
. nCName
允许从根目录搜索。
作为企业管理员组的成员,请小心执行此操作。
这是代码的示例。
/* Retreiving RootDSE
*/
string ldapBase = "LDAP://WM2008R2ENT:389/";
string sFromWhere = ldapBase + "rootDSE";
DirectoryEntry root = new DirectoryEntry(sFromWhere, "dom\\jpb", "PWD");
string configurationNamingContext = root.Properties["configurationNamingContext"][0].ToString();
/* Retreiving the root of all the domains
*/
sFromWhere = ldapBase + configurationNamingContext;
DirectoryEntry deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", "PWD");
DirectorySearcher dsLookForDomain = new DirectorySearcher(deBase);
dsLookForDomain.Filter = "(&(objectClass=crossRef)(nETBIOSName=*))";
dsLookForDomain.SearchScope = SearchScope.Subtree;
dsLookForDomain.PropertiesToLoad.Add("nCName");
dsLookForDomain.PropertiesToLoad.Add("dnsRoot");
SearchResultCollection srcDomains = dsLookForDomain.FindAll();
foreach (SearchResult aSRDomain in srcDomains)
{
/* For each root look for the groups containing my user
*/
string nCName = aSRDomain.Properties["nCName"][0].ToString();
string dnsRoot = aSRDomain.Properties["dnsRoot"][0].ToString();
/* To find all the groups that "user1" is a member of :
* Set the base to the groups container DN; for example root DN (dc=dom,dc=fr)
* Set the scope to subtree
* Use the following filter :
* (member:1.2.840.113556.1.4.1941:=cn=user1,cn=users,DC=x)
*/
/* Connection to Active Directory
*/
sFromWhere = "LDAP://" + dnsRoot + "/" + nCName;
deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", "PWD");
DirectorySearcher dsLookFor = new DirectorySearcher(deBase);
// you cancomplete the filter here (&(member:1.2.840.113556.1.4.1941:=CN=user1 Users,OU=MonOu,DC=dom,DC=fr)(cn=*2)
dsLookFor.Filter = "(member:1.2.840.113556.1.4.1941:=CN=user1 Users,OU=MonOu,DC=dom,DC=fr)";
dsLookFor.SearchScope = SearchScope.Subtree;
dsLookFor.PropertiesToLoad.Add("cn");
SearchResultCollection srcGroups = dsLookFor.FindAll();
foreach (SearchResult srcGroup in srcGroups)
{
Console.WriteLine("{0}", srcGroup.Path);
}
}
这只是一个概念证明,您必须完成:
使用using(){}
表单处理 DirectoryEntry 对象
异常管理

您可以在System.DirectoryServices.AccountManagement Namespace中给出的方法中找到您对解决问题方式的评论。这是一种递归解决方案。这一次,我使用属于 group2 (在第三个域中)的 group1 (在另一个域中)的用户进行测试,它似乎可以工作。
/* Retreiving a principal context
*/
Console.WriteLine("Retreiving a principal context");
PrincipalContext domainContext = new PrincipalContext(ContextType.Domain, "WM2008R2ENT:389", "dc=dom,dc=fr", "jpb", "PWD");
/* Look for all the groups a user belongs to
*/
UserPrincipal aUser = UserPrincipal.FindByIdentity(domainContext, "user1");
PrincipalSearchResult<Principal> a = aUser.GetAuthorizationGroups();
foreach (GroupPrincipal gTmp in a)
{
Console.WriteLine(gTmp.Name);
}
