如何从Active Directory检索SAMAccountName

Question

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.

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;
}

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)的长度最多为20个字符的名称-通常这是你的"Windows用户名"(例如Administrator) -但它不包括域名.由该组成的domain\username值不会存储在Active Directory中的任何位置!

如果您使用的是.NET 3.5及更高版本,则应该查看System.DirectoryServices.AccountManagement(S.DS.AM)命名空间.在这里阅读所有相关内容:

• 管理.NET Framework 3.5中的目录安全性主体
• System.DirectoryServices.AccountManagement上的MSDN文档

基本上,您可以定义域上下文并轻松查找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;
}

新的S.DS.AM使得在AD中与用户和群组玩游戏变得非常容易!

如果要搜索整组用户(或组或计算机),可以使用a PrincipalSearcher和"按示例查询"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.....          
}
