C# - How To Access Active Directory To Get The List Of Groups That A Certain User Belongs To
Aug 24, 2010
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've been searching for a solution to get a list of the AD Groups for at specific AD user. I'll need the current user logged in and would like to query by the username. The problem is that all the solutions I find on the web uses System.DirectoryServices - and I can't find the dll in my .Net 4.0 webproject (I only have System.DirectoryServices.AccountManagement) - so I can't use any of the examples that I've found. Is there a difference way to query the AD through 4.0 compared to 2.0? I could really use some examples, articles or just good advise to get moving - I'm kind of stuck at the moment.

I am having trouble using UserPrincipal.GetGroups in System.DirectoryServices.AccountManagement.
When I use the following code:
PrincipalSearchResult<Principal> groups = userPrincipal.GetGroups();
foreach (GroupPrincipal g in groups){
Console.WriteLine(g.DisplayName);
}
I get the error "The value for the property AttributeScopeQuery cannot be set" in the foreach loop. I also get the same error when using groups.Count()I have read things that indicate this may be due to having some Windows 2000 domain controllers in the domain and so meaning it does not support ASQ.
What is the best way of doing this? The best I have come up with, since most of the rest of my code is running fine using System.DirectoryServices.AccountManagement is using the GetUnderlyingObject method of the UserPrincipal to get a DirectoryEntry and enumerating the values of the memberOf attribute. Using LINQ the code is quite compact:
var groups = from string groupPath in
((DirectoryEntry)userPrincipal.GetUnderlyingObject()).Properties["memberOf"]
select new DirectoryEntry("LDAP://" + groupPath).Name.Replace("CN=", "");
foreach(groupName in groups){
Console.WriteLine(groupName);
}

I have a windows user accounts which i just created take XYZ for example.
This XYZ belongs to a User group and a custom group i created in Computer Management --> Local users and groups.
So in properties i see that the user belongs to the 2 groups.
Now i want to get those groups and display them. any suggestions???
i have done this but this is not right as it gives me the roles of SQL (i think)
here is what i did:
after logging in and impersonating i call the function
getUserGroups();
private void getUserGroups()
{
// collect the user domain and identity
string[] arr =
System.Web.HttpContext.Current.Request.
LogonUserIdentity.Name.Split('\');
// update the display to show
// the captured domain and user
if (arr.Length > 0)
{
new GUIUtility().LogMessageToFile("User Name" + arr[0].ToString());
new GUIUtility().LogMessageToFile("User Domain" + arr[1].ToString());
}
// create an arraylist and populate
// it with the list of groups that
// the current user belongs to
ArrayList al = new ArrayList();
al = GetGroups();
// check to see if the user belongs
// to a specific group and create
// a list of all of the user's groups
foreach (string s in al)
{
// add this one to the list
new GUIUtility().LogMessageToFile("Group" + s);
// check to see if the user
// belongs to a specific group
//if (s == "BXSWLT\SomeCustomGroup")
//{
// // change the label to show
// // there was a match
// lblMemberOfGroup.Text = "YES";
//}
}
}
public ArrayList GetGroups()
{
ArrayList groups = new ArrayList();
foreach (System.Security.Principal.IdentityReference group in
System.Web.HttpContext.Current.Request.LogonUserIdentity.Groups)
{
groups.Add(group.Translate(typeof
(System.Security.Principal.NTAccount)).ToString());
}
return groups;
}
the Result i get is:
9/8/2010 5:57:22 PM: User Name NT AUTHORITY.
9/8/2010 5:57:22 PM: User Domain IUSR.
9/8/2010 5:57:22 PM: Group Everyone.
9/8/2010 5:57:22 PM: Group BUILTINUsers.
9/8/2010 5:57:22 PM: Group NT AUTHORITYAuthenticated Users.
9/8/2010 5:57:22 PM: Group NT AUTHORITYThis Organization.
9/8/2010 5:57:22 PM: Group LOCAL.

I have an ASP.NET 3.5 application using Windows Authentication and implementing our own RoleProvider.
Problem is we want to restrict access to a set of pages to a few thousand users and rathern than inputing all of those one by one we found out they belong to an AD group.
The answer is simple if the common group we are checking membership against the particular user is a direct member of it but the problem I'm having is that if the group is a member of another group and then subsequently member of another group then my code always returns false.
For example: Say we want to check whether User is a member of group E, but User is not a direct member of *E", she is a member of "A" which a member of "B" which indeed is a member of E, therefore User is a member of *E"
One of the solutions we have is very slow, although it gives the correct answer
using (var context = new PrincipalContext(ContextType.Domain))
{
using (var group = GroupPrincipal.FindByIdentity(context, IdentityType.Name, "DL-COOL-USERS"))
{
var users = group.GetMembers(true); // recursively enumerate
return users.Any(a => a.Name == "userName");
}
}
The original solution and what I was trying to get to work, using .NET 3.5 System.DirectoryServices.AccountManagement and it does work when users are direct members of the group in question is as follows:
public bool IsUserInGroup(string userName, string groupName)
{
var cxt = new PrincipalContext(ContextType.Domain, "DOMAIN");
var user = UserPrincipal.FindByIdentity(cxt, IdentityType.SamAccountName, userName);
if (user == null)
{
return false;
}
var group = GroupPrincipal.FindByIdentity(cxt, groupName);
if (group == null)
{
return false;
}
return user.IsMemberOf(group);
}
The bottom line is, we need to check for membership even though the groups are nested in many levels down.

I'm trying to get the groups a user is member of from an Open Ldap using vb.net 3.5.
Although so far I have managed to connect to the ldap server and get the user's info like sn, givenname, description, mail, adspath,
I have absolutely no information about the user's groups.
My code is like this:
Dim oEntry as New DirectoryEntry
Dim oSearcher as New DirectorySearcher
oEntry = New DirectoryEntry("LDAP://myServer/ou=test, dc=example, dc=com", username, pwd, AuthenticationTypes.ServerBind)
oSearcher = New DirectorySearcher(oEntry, "(uid=" & uName & ")")
oResult = oSearcher.FindOne()
if not oResult is Nothing then
Dim ADUser as DirectoryEntry
ADUSer = oResult.GetDirectoryEntry()
end if
Well, ADUser has no info on user membership whatsoever.
Am I doing something wrong? Should I use System.DirectoryServices.Protocols as I saw someone mentioning instead
of System.DirectoryServices or is .Protocols just for Framework 2.0?

I have a web app that uses AD to authenticate the user which works great. But i received a request where a user that is outside of the Ad needs access to the application.
Is there a way to add this user manually (Maybe in web.config) to allow them to access the application?

I have read countless forums and found nothing so for so apparently what I need is an unusual request.I need a code snippet that will iterate through an AD domain account and display all properties for a given user.Has anyone ever built such a script?
If there is a code snippet that displays just the available properties of a user object, this would be sufficient. I am trying to build an application to add users to our LDAP and need to populate all our specific values however I don't have the specific property names to populate.

My System Have 2 Computer:
Frist Computer act as A domain Controller that has a Active Directory,RADIUS Server,DHCP and DNS
Second Computer act as A Web Server and use Microsoft Visual Studio Team System 2008
I create a website to add user in active directory. I have 3 file:
1.Default.aspx - Let user fill their privacy information
2.ViewRegisterdata.aspx - Let user confirm their information before it's added to active directory. In this file,there is a Viewregisterdata.aspx.cs which collect user information and send to Class1.cs when users click confirm button.
3.Class1.cs - Do the process in adding user in active directory
I have a problem with a second and third files. When I run the website and go to a second page that is a ViewRegisterdata.aspx and then press a confirm button,it shows an error.
Although I inactivate a code section that do adding user to active directory and write a code to show a value that is sent from A ViewRegisterdata.aspx,It still shows a ViewDataregister.aspx and not show a Windows console.It seems it cannot send user information from a ViewRegisterData.aspx despite I include a Class1.cs into the file already
