How To List Windows Users And Groups
Aug 18, 2010
I have a ASP.NET Website project and I need to list all the users and their groups on my Windows system. I have set the identity impersonation to true and provided the username and password of the admin in the web.config. Where do I start?
Update:
I have the following code at the moment -
var machine = new DirectoryEntry("WinNT://<IP ADDRESS>");
foreach (DirectoryEntry child in machine.Children)
{
// get the child's group(s).
}
When I debug, I can see the list of users in machine.Children. How do I find the group(s) that this user belongs to?

I wrote this to get the groups a particular user belongs to:
DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
DirectoryEntry user = AD.Children.Find(completeUserName, "user");
object obGroups = AD.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
listOfMyWindowsGroups.Add(obGpEntry.Name);
}
for (int j = 0; j < listOfMyWindowsGroups.Count; j++)
{
//ex
}
How is it possible to retrieve all the groups in windows and not just for a particular user?

I need to create a site that is Roles based and can use AD groups and Users. I found Scott Mitchell's tutorials for setting up "role-based-authorization-cs" [URL]
I've changed to using Windows auth. instead of forms and am pointing it to a remote SQL Database. I can successfully add a user/password/email etc. (although I believe the password and email sections aren't required and would like to remove them as options).
When I create a user (usera) and login to a windows box as usera the menu displays correctly based on the Roles I've added the user to in the SQL Database.
When I add an AD Group and add it to the same Role the menu's that are displayed do not match that of usera.
I'd like to be able to add entire AD groups (They can obviously change so it needs to be dynamic in some way), as well as add individual AD users to Roles. I'd prefer to do this via a Web interface.
My questions are.
1. Am I going about this the right way?
2. If I'm not what would be a better way?
3. If I am what do I need to do to allow ADGroup lookup?

I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.
Here is the membership provider definition from web.config:
[code]....
So, obviously, I have a Sql Server database that contains the users and roles for the web app. I'd like to create a separate windows app that references the web app assembly, and use the configured MembershipProvider, RoleProvider, and machineKey to create users, assign users to roles, etc. If that's not possible, I can duplicate the configuration settings from web.config within the windows app. But I don't know how to do this either.

I'm not sure the best way to explain this but I want to take results from a stored procedure and list them but not in a grid. I am listing user profiles and I want to display a picture, name, description and other info from each record. But I want each in a group. How is this done in asp.net?

I am "DomainMyDomainUserName" If I do this:
[Code]....
I can access the website I've created on my local machine in debug mode; and with my domain account as a local administrator, if I do this:
[Code]....
I can still access the website; and with my domain account in a Domain Group named "DomainDomainLocalSecurityGroup", if I do this:
[Code]....
I can still access the website; HOWEVER, if I create a Local Group on my machine named "LocalMachineGroup" and I add "DomainMyDomainUserName" to this group and I do this:
[Code]....
I get an Access Denied error trying to access the website. What I want to do is, have a group on my local machine (for testing), on a test web server, and on a production web server named "MyWebsiteUserAccess" with the same Domain Group (filled with Domain Users allowed access to the site) in all of these local groups; so that when I test the web application on my local machine, on my test web server and on my production web server, I don't have to change the Web.config file to have it work on each AND if the Domain Group name ever has to change, it won't affect access to the website.
What am I overlooking or is this even possible to do this way? I understand that there is a way to do Role Management through ASP.NET but I don't understand that well enough yet to implement that (and will probably go that route once I've done the research on how to best implement it for purpose of access control of this intranet site).

In C#, how do i access Active Directory to get the list of groups that a certain user belongs to?
The user details are in the form:
"MYDOMAINmyuser"
I've been following the instructions from here but they only work if i have the user details in the form:
"LDAP://sample.com/CN=MySurname MyFirstname,OU=General,OU=Accounts,DC=sample,DC=com"
So maybe what i'm asking is, how to get from the first, shorter, form to the fully qualified form below?

I have a user that when I attempt to enumerate her groups using either System.Security.Principal.WindowsIdentity.GetCurrent().Groups on user's computer
or System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups on the IIS server, I get a list of their old groups, not their new. I have checked the DC that they authenticate to and the ASP.NET page is running inside a SharePoint instance so the LogonUserIdentity most like is being provided from there Kerberos ticket.
Should I be looking up the groups directly from the AD instead of relying on the WindowsIdentity or LogonUserIdentity?

i have a code to get the groups a user belongs to.
try
{
DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));
DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");
object obGroups = user.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
// Create object for each group.
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
listOfMyWindowsGroups.Add(obGpEntry.Name);
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
return false;
}
the above code works fine when i have to find the groups of a local user but
for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups.
Research
I did some finding and got that i am being returned the primary group of the domain user
called "Domain User" group
but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions
another code using LDAP
string domain = Environment.UserDomainName;
DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
DirectorySearcher search = new DirectorySearcher();
search.SearchRoot = DE;
search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name
search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups
try
{
SearchResult result = search.FindOne(); // Grab the records and assign them to result
if (result != null)
{
DirectoryEntry theUser = result.GetDirectoryEntry();
theUser.RefreshCache(new string[] { "tokenGroups" });
foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
{
System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);
DirectorySearcher sidSearcher = new DirectorySearcher();
sidSearcher.SearchRoot = DE;
sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
sidSearcher.PropertiesToLoad.Add("distinguishedName");
SearchResult sidResult = sidSearcher.FindOne();
if (sidResult != null)
{
listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]);
}
}
}
else
{
new GUIUtility().LogMessageToFile("no user found");
}
return true;
}
catch (Exception ex)
{
new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
return false;
}
this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...?

In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))

Technologies involved:
ASP.NET Web-forms
Javascript (jQuery for instance)
Case,To make it clearer let's give the Stackoverflow Users list as an example. This list can be manipulated at client-side. I can search, page and so forth. So obviously we would need to call jQuery.ajax to retrieve the HTML of each page given a search. Alright. Now this leaves me with the first question:
What is the best way to render the response for the jQuery.ajax at server-side? I can't use templates I suppose, so the most obvious solution I think is to create the HTML tags as server-controls and render them as the result of an ASHX request? Nice. That solved we have yet another problem:
When the user first enters the Authors List the first list page should already come from the server completely rendered alright? Of course we could render the first page as well as an ajax call but I don't think it's better. This time I CAN use templates to render the list but this template couldn't be reused in case 1. What do I do?
Now the final question: Now we have 2 rendering strategies: 1) Client and 2) Server. How do I reuse code for the 2 renderings?

The site is running on my local IIS 6.1. I Would like to add some features to pull information from our AD. My AD code works on many other projects and on my dev server. Here are my attempts at writing out the username:
Response.Write("1. " + this.Request.LogonUserIdentity.Name);
Response.Write("2. " + Request.ServerVariables["Auth_User"]);
Response.Write("3. " + WindowsIdentity.GetCurrent().Name.ToString());
The results I get are:
NT AUTHORITYIUSR
administrator
NT AUTHORITYNETWORK SERVICE
How can I get at the actual windows username like ourdomain/username

I need to look for an example of a web application, preferably ASP.NET but any otherweb language will do, that lets Mac and Windows users change their AD password.
Any technique, application, or source code will be great.
P.S: our Macs are not connected to AD and we also have Windows users.

We are observing some strange behaviour in our web server logs where where the Identity of the currently logged in user seems to be getting swapped with another user. I will describe our set up before explaining further.
We are running an asp.net web site (v3.5 of the framework) on 2 Windows 2008 web servers and use forms authentication.They are load balanced using a separate server running Apache 2.2 on Linux (Cent OS 5). The load balancing simply attaches a cookie to a user and directs them to a particular server for each subsequent request.
We notice on occasion patterns in the log like this (details obfuscated)
First Log Entry
UserName - customer1@x.com
UserId - 1111
WebPage - page1
IP - ip1
Time - 2010-06-29 12:56:20.750
SessionId - h3uyz2fsdfegugjy452sdz0far.........
We are using forms authentication using the standard asp.net forms authentication framework (the standard login control and we implemented a custom membership provider).
The UserName is the Windows identity retrieved using "HttpContext.Current.User.Identity.Name" The UserId is the database Id set in the session. The sessionId is retrieved using "HttpContext.Current.Session.SessionID"
As you can see the same Windows identity is the same for 2 different users, under different IP addresses and with different session id's, hitting the site about the same time. We checked and the IP's were from totally different locations. The wrong windows identity seems to be getting recorded. UserId 2222 should have a different username recorded.
Since it happens very occasionally, the code is standard and has not changed substantially for some time we don't "think" it is a coding error. We presume either a problem with the load balancer or some problem in the web server. I have never heard of such problems in asp.net before.
The forms authentication entry in the web.config is
authentication mode="Forms"
forms loginUrl="LoginPage.aspx" name=".ASPXFORMSAUTH"

On our production servers, the admins created a WebUser active directory account which is users for anonymous access to IIS and is also used to authenticate database access with our SQL Server instances using Integrated Security=SSPI in the connection string and identity impersonate="true" in the web.config.
I've often come across situations where I would like to or even need to use forms authentication. However, I using forms authentication, Integrated Security seems to use the logged in user's credentials to authenticate against the database. In these cases I have changed the connection string to use the credentials of a SQL Server users instead. I would prefer to not have a hard coded username and password in the connection string or rather worse in code. Is it possible to use forms authentication just for user authentication for users and windows authentication with the IIS user for database access? What would be the best practice in such a situation?

I am trying to create an Intranet application and I want my users to be able to log in with their windows account. However my organisation has over 150000 employees but I only want the 10-12 people in my department to be able to log in.
How do I do this? Do I need to store the 10-12 users in a database?

I am using windows authentication in my web application. All we need is when the application will be executed it will launch login.aspx page. If users put correct userid and password(checked from active server directory) it will be redirected to a difference page. But if any unauthenticated user tries to access any other page in the application by typing the Url on the address bar it will be again redirected to the login page. We have to do this by changing our web.config file.I can achieve this using form authentication but not windows. But our requirement is windows. The requirement is very basic but all effort is just not working.
