In asp.net/c#, is there a way to find all of the AD level user groups from a given domain in which the logged in user belongs to? E.g. I have a domain level user and few groups. I want to pass in the domain name and the logged in user's user name and get a list of AD groups of that particular domain.

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...?
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).
I am using C# and ASP.NET for this. We receive a lot of "strange" requests on our IIS 6.0 servers and I want to log and catalog these by domain. Eg. we get some strange requests like these:
[URL]
the latter three are kinda obvious, but I would like to sort them all into one as [URL] IS hosted on our servers. The rest isnt, sorry :-) how to retrieve [URL] from the above. Secondly I would like to match the m., wap., iphone etc into a group, but thats probarbly just a quick lookup in a list of mobile shortcuts. Could handcode this list for a start. But is regexp the answer here or is pure string manipulation the easiest way? I was thinking of "splitting" the URL string by "." and the look for item[0] and item[1]...
i want to get the domain extention (at least i hope it is called this way) from the site name the user is currently on. so from [URL] it's co.uk and [URL] etc. especially the ones with the double name (like co.uk) gives me headaches.... EDIT as i understand from the comments, co.uk is not a top level domain? that makes life easier! EDIT new name (top level domain) in the title
View 4 Replieshow do I fetch "fr" out of this? JUST "fr" actually what I am trying to do is change masterpages at runtime after detecting a visitor's country..Yes I can use the countryCode variable which is there in some other class but thot may be I can do it like this only..just wanted to try..logic basically is:-
if(its "fr")
{
//apply masterpage 1
}
if(its "in")
{
//apply masterpage 2
}
Is it possible ? What will be the right way anyway ? Making that class that contains CountryCode variable as a utility class and using the variable from there in my new class OR fetch this value "fr" or "in" off the URL ?? How do I do this ? Is it possible?

View 2 RepliesI 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 use this code to get the groups of the current user. But I want to manually give the user and then get his groups. How can I do this?
[code]....
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.

Is there a way to get the groups a local user belongs to using directory services?
without using activedirectory or domain in it because i want for the local machine only and not for a domain.
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.
View 4 RepliesI 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.
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 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 am working in asp.net and csharp, we have 10 user, but certain user only need to put dataentry. how to enable and disable based on the user to access certain form ,like add, modify view options.

View 1 RepliesI'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.

I have a summary page that has an Add New Record button, andEdit Record butto and a Delete Record button.Every user has ReadOnly access.However, only users with administrators Access Level can add, edit, delete, view.Users with Staffers Access Level can only Add records but cannot delete or edit.So, basically, 2 access Levels, Administrators, Staffers.Administrators can view, add, delete, update records.The rest, Staffers, can only view and Add records.I am struggling to figure this out.I have done this a ton of times using Classic ASP, something like:
If AccessLevel <> "Administrator" Then
Response.Redirect"login.asp" 'so if user has admin password, s/he ccan log in with that.
End if
[code]...
4 different groups will be using the system, each will be redirected to their own summary page based on their groupNumber.All I just want now is to ensure that a user from a particular group is redirected to his/her summary page, then that user is checked again against AccessLevel (view, edit, delete, update).
