How to retrieve SAMAccountName from Active Directory
提问by unknownUser
I implemented a method that returns a list of Active Directory users, I would like to retrieve SAMAccountName like this Domain\Administrator.
我实现了一个返回 Active Directory 用户列表的方法，我想像这样检索 SAMAccountName Domain\Administrator。
This is the method I use:
这是我使用的方法：
public Collection<software_user> GetUsersFromAD(String adConnectionString)
{
var users = new Collection<software_user>();
using (var directoryEntry = new DirectoryEntry(adConnectionString))
{
var directorySearcher = new DirectorySearcher(directoryEntry);
directorySearcher.Filter = "(&(objectClass=user))";
var propertiesToLoad = new[]
{
"SAMAccountName",
"displayName",
"givenName",
"sn",
"mail",
"userAccountControl",
"objectSid"
};
directorySearcher.PropertiesToLoad.AddRange(propertiesToLoad);
foreach (SearchResult searchEntry in directorySearcher.FindAll())
{
var userEntry = searchEntry.GetDirectoryEntry();
var ldapUser = new software_user();
ldapUser.User_name = NullHandler.GetString(userEntry.Properties["displayName"].Value);
if (string.IsNullOrEmpty(ldapUser.User_name))
continue;
ldapUser.User_name = NullHandler.GetString(userEntry.Properties["SAMAccountName"].Value);
ldapUser.email = NullHandler.GetString(userEntry.Properties["mail"].Value);
ldapUser.user_shortname = NullHandler.GetString(userEntry.Properties["givenName"].Value);
var userAccountControl = (int)userEntry.Properties["userAccountControl"].Value;
//ldapUser.IsActive = (userAccountControl & UF_ACCOUNTDISABLE) != UF_ACCOUNTDISABLE;
var sid = new SecurityIdentifier((byte[])userEntry.Properties["objectSid"][0], 0).Value;
//ldapUser.SId = sid;
users.Add(ldapUser);
}
}
return users;
}

First off:Domain\Administratoris NOTa SAM account name! The SAM account name is a unique (over the whole domain) name of up to 20 characters in length - typically it's your "Windows user name" (e.g. Administrator) - but it does NOTinclude the domain name. That value made up of domain\usernameis NOTstored in Active Directory anywhere!
第一关：Domain\Administrator是不是一个SAM帐户名！SAM帐户名是唯一的（在整个域）最多20个字符长的名字-通常这是你的“Windows用户名”（例如Administrator） -但它不包括域名。组成的domain\username值不会存储在 Active Directory 中的任何地方！
If you're on .NET 3.5 and up, you should check out the System.DirectoryServices.AccountManagement(S.DS.AM) namespace. Read all about it here:
如果您使用 .NET 3.5 及更高版本，则应查看System.DirectoryServices.AccountManagement(S.DS.AM) 命名空间。在这里阅读所有相关信息：
- Managing Directory Security Principals in the .NET Framework 3.5
- MSDN docs on System.DirectoryServices.AccountManagement
Basically, you can define a domain context and easily find users and/or groups in AD:
基本上，您可以定义域上下文并轻松找到 AD 中的用户和/或组：
// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// find a user
UserPrincipal user = UserPrincipal.FindByIdentity(ctx, "SomeUserName");
if(user != null)
{
// do something here....
string samAccountName = user.SamAccountName;
}
The new S.DS.AM makes it really easy to play around with users and groups in AD!
新的 S.DS.AM 使在 AD 中与用户和组一起玩变得非常容易！
If you want to search for a whole group of users (or groups or computers), you can use a PrincipalSearcherand a "query-by-example" principal to do your searching:
如果要搜索整个用户组（或组或计算机），可以使用 aPrincipalSearcher和“query-by-example”主体进行搜索：
// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// define a "query-by-example" principal - here, we search for a UserPrincipal
// and with the last name (Surname) of "Miller"
UserPrincipal qbeUser = new UserPrincipal(ctx);
qbeUser.Surname = "Miller";
// create your principal searcher passing in the QBE principal
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);
// find all matches
foreach(var found in srch.FindAll())
{
// do whatever here - "found" is of type "Principal" - it could be user, group, computer.....

You can translate a user as a Distinguished name to DOMAIN\SAMaccount form using the Object's SID, and the System.Security.Principal.SecurityIdentifier.Translate command.
您可以使用对象的 SID 和 System.Security.Principal.SecurityIdentifier.Translate 命令将用户作为专有名称转换为 DOMAIN\SAMaccount 形式。
public Collection<software_user> GetUsersFromAD(String adConnectionString)
{
var users = new Collection<software_user>();
using (var directoryEntry = new DirectoryEntry(adConnectionString))
{
var directorySearcher = new DirectorySearcher(directoryEntry);
directorySearcher.Filter = "(&(objectClass=user))";
var propertiesToLoad = new[]
{
"SAMAccountName",
"displayName",
"givenName",
"sn",
"mail",
"userAccountControl",
"objectSid"
};
directorySearcher.PropertiesToLoad.AddRange(propertiesToLoad);
foreach (SearchResult searchEntry in directorySearcher.FindAll())
{
var userEntry = searchEntry.GetDirectoryEntry();
var ldapUser = new software_user();
ldapUser.User_name = NullHandler.GetString(userEntry.Properties["displayName"].Value);
if (string.IsNullOrEmpty(ldapUser.User_name))
continue;
ldapUser.User_name = NullHandler.GetString(userEntry.Properties["SAMAccountName"].Value);
ldapUser.email = NullHandler.GetString(userEntry.Properties["mail"].Value);
ldapUser.user_shortname = NullHandler.GetString(userEntry.Properties["givenName"].Value);
var userAccountControl = (int)userEntry.Properties["userAccountControl"].Value;
//ldapUser.IsActive = (userAccountControl & UF_ACCOUNTDISABLE) != UF_ACCOUNTDISABLE;
SecurityIdentifier sid = new SecurityIdentifier((byte[])userEntry.Properties["objectSid"][0], 0).Value;
--> NTAccount account = (NTAccount) sid.Translate(typeof(NTAccount));
--> ldapUser.User_name = account.ToString();
//ldapUser.SId = sid;
users.Add(ldapUser);
}
}
return users;
}
