C#从广告中获得fsmo角色

Question

有没有办法从活动目录中获得使用C#的FSMO角色？，即使可能的话，使用LDAP查询也能工作。

在很多博客上都有大量的VB脚本代码。但不是C#。

和如何找到DC是PDC还是不PDC？

谢谢

我原以为很难找到这份工作，但最终还是很容易的。我正在张贴代码，以防将来有人需要这个。

System.DirectoryServices.ActiveDirectory.Domain dom = System.DirectoryServices.ActiveDirectory.Domain.GetCurrentDomain();
System.DirectoryServices.ActiveDirectory.DomainController pdcdc = dom.PdcRoleOwner;
foreach (System.DirectoryServices.ActiveDirectory.DomainController dc in dom.DomainControllers)
                {
                    foreach (ActiveDirectoryRole role in dc.Roles)
                    {
                        Console.WriteLine("dc : {0} role : {1}", dc.Name,role.ToString());
                    }
                }

您可以通过使用LDAP的方法从Active Directory找到5个灵活的单一主操作(FSMO)角色。可以在Active的不同命名上下文中找到它们寻找属性fsmoRoleOwner。您可以在这里找到用C#编写的3条LDAP搜索。小心，代码不那么干净，这只是概念的一种证明。

确定FSMO角色持有者是一个很好的来源。

static void Main(string[] args)
{
  /* Retreiving RootDSE informations
   */
  string ldapBase = "LDAP://WM2008R2ENT:389/";
  string sFromWhere = ldapBase + "rootDSE";
  DirectoryEntry root = new DirectoryEntry(sFromWhere, "dom\\jpb", "pwd");
  string defaultNamingContext = root.Properties["defaultNamingContext"][0].ToString();
  string schemaNamingContext = root.Properties["schemaNamingContext"][0].ToString();
  string configurationNamingContext = root.Properties["configurationNamingContext"][0].ToString();

  /* Search the 3 domain FSMO roles
   */
  sFromWhere = ldapBase + defaultNamingContext;
  DirectoryEntry deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", "pwd");

  DirectorySearcher dsLookForDomain = new DirectorySearcher(deBase);
  dsLookForDomain.Filter = "(fsmoRoleOwner=*)";
  dsLookForDomain.SearchScope = SearchScope.Subtree;
  dsLookForDomain.PropertiesToLoad.Add("fsmoRoleOwner");
  dsLookForDomain.PropertiesToLoad.Add("distinguishedName");

  SearchResultCollection srcDomains = dsLookForDomain.FindAll();
  foreach (SearchResult sr in srcDomains)
  {
    /* For each root look for the groups containing my user
     */
    string fsmoRoleOwner = sr.Properties["fsmoRoleOwner"][0].ToString();
    string distinguishedName = sr.Properties["distinguishedName"][0].ToString();
    Regex srvNameRegEx = new Regex("^CN=NTDS Settings,CN=(.*),CN=Servers,.*$");
    Match found = srvNameRegEx.Match(fsmoRoleOwner);

    if (distinguishedName == defaultNamingContext)
      Console.WriteLine("PDC is {0}", found.Groups[1].Value);
    else if (distinguishedName.Contains("RID Manager"))
      Console.WriteLine("RID Manager is {0}", found.Groups[1].Value);
    else
      Console.WriteLine("Infrastructure Manager is {0}", found.Groups[1].Value);
  }

  /* Search the schema FSMO role
  */
  sFromWhere = ldapBase + schemaNamingContext;
  deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", "pwd");

  dsLookForDomain = new DirectorySearcher(deBase);
  dsLookForDomain.Filter = "(fsmoRoleOwner=*)";
  dsLookForDomain.SearchScope = SearchScope.Subtree;
  dsLookForDomain.PropertiesToLoad.Add("fsmoRoleOwner");
  dsLookForDomain.PropertiesToLoad.Add("distinguishedName");

  srcDomains = dsLookForDomain.FindAll();
  foreach (SearchResult sr in srcDomains)

    string distinguishedName = sr.Properties["distinguishedName"][0].ToString();
    Regex srvNameRegEx = new Regex("^CN=NTDS Settings,CN=(.*),CN=Servers,.*$");
    Match found = srvNameRegEx.Match(fsmoRoleOwner);

    if (distinguishedName.Contains("Schema"))
      Console.WriteLine("Schema Manager is {0}", found.Groups[1].Value);
  }

  /* Search the domain FSMO role
  */
  sFromWhere = ldapBase + configurationNamingContext;
  deBase = new DirectoryEntry(sFromWhere, "dom\\jpb", "pwd");

  dsLookForDomain = new DirectorySearcher(deBase);
  dsLookForDomain.Filter = "(fsmoRoleOwner=*)";
  dsLookForDomain.SearchScope = SearchScope.Subtree;
  dsLookForDomain.PropertiesToLoad.Add("fsmoRoleOwner");
  dsLookForDomain.PropertiesToLoad.Add("distinguishedName");

  srcDomains = dsLookForDomain.FindAll();
  foreach (SearchResult sr in srcDomains)
  {
    /* For each root look for the groups containing my user
     */
    string fsmoRoleOwner = sr.Properties["fsmoRoleOwner"][0].ToString();
    string distinguishedName = sr.Properties["distinguishedName"][0].ToString();
    Regex srvNameRegEx = new Regex("^CN=NTDS Settings,CN=(.*),CN=Servers,.*$");
    Match found = srvNameRegEx.Match(fsmoRoleOwner);

    if (distinguishedName.Contains("Partitions"))
      Console.WriteLine("Domain Manager is {0}", found.Groups[1].Value);
  }
