Hi All,

I am very new to working Active directory. After spending some time on web i was able to get code for getting users from active directory using DirectorySearcher class. However i am facing hard time in getting a list of all supported clauses and keywords of search.

The only link i was able to get is https://msdn.microsoft.com/en-us/library/aa746475(v=vs.85).aspx. But got only few keywords.

Kindly share links / list of keywords and clauses. Below are some i found;

&(objectClass=user)
(objectCategory=person)
(manager=...)
(!msExchResourceMetaData=ResourceType:Room)
(!userAccountControl:1.2.840.113556.1.4.803:=2))

Also i tried creating a org chart using Visio and then with DirectorySearcher code. The visio files excludes virtual accounts such as feedback@abc,.com, meeting rooms, etc. but my Directory searcher code get them as welFrown . Kindly help.

0	Try using PrincipalSearcher( available from .NET 3.5 onwards) An example public static Task<IEnumerable<TestUserModelClass>> GetUsers(//Apply your filters) { 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; }); } Hope that helps -- Thanks & Regards, RNA Team Shoab.Shah, if this helps please login to Mark As Answer. \| Alert Moderator

An example

public static Task<IEnumerable<TestUserModelClass>> GetUsers(//Apply your filters)
{
    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;
    });
}

Hope that helps

0	Two things: There are no groups associated with an OU - an OU is a container which contains users, computers, groups etc. (like a directory that contains files). Is that what you mean? You want to enumerate the group contained inside a given OU?? if so: you're not calling the constructor for the PrincipalContext properly. If you check the MSDN documentation on PrincipalContext constructors, you'll see that the one you're using is the one with a ContextType and a name which stands for the domain name of the context you want to bind to: var ctx = new PrincipalContext(ContextType.Domain,"MyOU"); This binds to the MyOU domain - and it binds right at the root of that domain tree. What you're probably looking for is the constructor with three parameters - a ContextType and two strings - the first one being the domain name as above, and the second one being the start location of your search. So change your PrincipalContext construction to: var ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN", "OU=MyOU"); and then search again - now you should get only groups that are contained inside the OU=MyOU container.
