How to specify Windows users and groups in ASP.NET?

Question

I have an ASP.NET Website project, and I need to list all users and their groups on my Windows system. I set the identity impersonation to true and provided the administrator username and password in the web.config file. Where to begin?

Thanks in advance.

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 group(s). } 

When I debug, I see a list of users in machine.Children. How to find the group (s) to which this user belongs?

This article talks about how to talk to Active Directory and you have to find where you want to go: http://www.codeproject.com/KB/system/everythingInAD.aspx

To get users, you would do something like this:

 public List<string> GetUserList() { string DomainName=""; string ADUsername=""; string ADPassword=""; List<string> list=new List<string>(); DirectoryEntry entry=new DirectoryEntry(LDAPConnectionString, ADUsername, ADPassword); DirectorySearcher dSearch=new DirectorySearcher(entry); dSearch.Filter="(&(objectClass=user))"; foreach(SearchResult sResultSet in dSearch.FindAll()) { string str=GetProperty(sResultSet, "userPrincipalName"); if(str!="") list.Add(str); } return list; }

You probably want to start by supporting DirectoryEntry and Active Directory in .net.

Here's a good resource: http://www.codeproject.com/KB/system/everythingInAD.aspx

Local access is the same even if you are not in a domain:

 DirectoryEntry localMachine = new DirectoryEntry("WinNT://" + Environment.MachineName); DirectoryEntry admGroup = localMachine.Children.Find("administrators", "group"); object members = admGroup.Invoke("members", null); foreach (object groupMember in (IEnumerable)members) { DirectoryEntry member = new DirectoryEntry(groupMember); //... }
