使用PrincipalSearcher查找具有"or“参数的用户

Question

是否可以使用System.DirectoryServices.AccountManagement.PrincipalSearcher根据多个参数使用"or“(而不是"and")进行搜索。

即

// This uses an and
//(&(objectCategory=person)(!UserAccountControl:1.2.840.113556.1.4.803:=2)(&(SAMAccountName=tom*)(DisplayName=tom*)))
var searchPrinciple = new UserPrincipal(context);
searchPrinciple.DisplayName =  "tom*";
searchPrinciple.SamAccountName = "tom*";

var searcher = new PrincipalSearcher();
searcher.QueryFilter = searchPrinciple;

var results = searcher.FindAll();

我想要一个类似的搜索(在LDAP中)使用PrincipalSearcher (而不是DirectorySearcher)

// (&(objectCategory=person)(!UserAccountControl:1.2.840.113556.1.4.803:=2)(|(SAMAccountName=tom*)(DisplayName=tom*)))

Answer 1

这显然是不可能的，这里有一个解决方法：

List<UserPrincipal> searchPrinciples = new List<UserPrincipal>();
searchPrinciples.Add(new UserPrincipal(context) { DisplayName="tom*"});
searchPrinciples.Add(new UserPrincipal(context) { SamAccountName = "tom*" });
searchPrinciples.Add(new UserPrincipal(context) { MiddleName = "tom*" });
searchPrinciples.Add(new UserPrincipal(context) { GivenName = "tom*" });

List<Principal> results = new List<Principal>();
var searcher = new PrincipalSearcher();
foreach (var item in searchPrinciples)
{
    searcher = new PrincipalSearcher(item);
    results.AddRange(searcher.FindAll());
}

不一定像其他一些答案那样清晰，但这里是我如何在我正在工作的项目中实现这一点的。我希望这两个搜索都是异步运行的，以尝试减少由于运行两个AD查询而导致的速度减慢。

public async static Task<List<ADUserEntity>> FindUsers(String searchString)
{
    searchString = String.Format("*{0}*", searchString);
    List<ADUserEntity> users = new List<ADUserEntity>();

    using (UserPrincipal searchMaskDisplayname = new UserPrincipal(domainContext) { DisplayName = searchString })
    using (UserPrincipal searchMaskUsername = new UserPrincipal(domainContext) { SamAccountName = searchString })
    using (PrincipalSearcher searcherDisplayname = new PrincipalSearcher(searchMaskDisplayname))
    using (PrincipalSearcher searcherUsername = new PrincipalSearcher(searchMaskUsername))
    using (Task<PrincipalSearchResult<Principal>> taskDisplayname = Task.Run<PrincipalSearchResult<Principal>>(() => searcherDisplayname.FindAll()))
    using (Task<PrincipalSearchResult<Principal>> taskUsername = Task.Run<PrincipalSearchResult<Principal>>(() => searcherUsername.FindAll()))
    {
        foreach (UserPrincipal userPrincipal in (await taskDisplayname).Union(await taskUsername))
            using (userPrincipal)
            {
                users.Add(new ADUserEntity(userPrincipal));
            }
    }

    return users.Distinct().ToList();
}

我的ADUserEntity类有一个基于SID的相等检查。我试图将Distinct()添加到两个搜索器结果的Union()中，但没有成功。

我欢迎对我的回答提出任何建设性的批评，因为我想知道是否有任何方法可以改进它。

我知道这有点晚了，但这是我在搜索广告时使用的结构：

public static Task<IEnumerable<SomeUserModelClass>> GetUsers(//Whatever filters you want)
{
    return Task.Run(() =>
    {
        PrincipalContext context = new PrincipalContext(ContextType.Domain);
        UserPrincipal principal = new UserPrincipal(context);
        principal.Enabled = true;
        PrincipalSearcher searcher = new PrincipalSearcher(principal);

        var users = searcher.FindAll().Cast<UserPrincipal>()
            .Where(x => x.SomeProperty... // Perform queries)
            .Select(x => new SomeUserModelClass
            {
                userName = x.SamAccountName,
                email = x.UserPrincipalName,
                guid = x.Guid.Value
            }).OrderBy(x => x.userName).AsEnumerable();

        return users;
    });
}
