Security :: How To Protect Form Controls Based On Active Directory Group
Feb 12, 2011
I have a requirement to make parts of forms (and sometimes the entire form) read-only based on the user's active-directory group. I already have integrated AD into the dynamic menu, so that users cannot view certain menu itmes based on their AD group - and this is working fine; however, now they want to get down to the control-level on the forms. The first way that comes to mind is for me to just grab the AD groups for the users and then loop through them, and write my own code to make controls read-only or enabled. Is this a good way to do it, or is there another way? Also, while we're on the topic, is there an easy way to protect an entire form, or maybe an entire panel?

I am getting the details from groups but some groups have data but did not return any data is there any problem with this code. some groups have returned data.
CN=Tets App_Reviewer,OU=Tets Appl Groups,OU=District Wide Groups,DC=tets,DC=com;
Tets App_Reviewer is the group name
public List<ADUserDetail> GetUserFromGroup(String groupName)
{
List<ADUserDetail> userlist = new List<ADUserDetail>();
try
{
_directoryEntry = null;
DirectorySearcher directorySearch = new DirectorySearcher(SearchRoot);
directorySearch.Filter = "(&(objectClass=group)(SAMAccountName=" + groupName + "))";
SearchResult results = directorySearch.FindOne();
if (results != null)
{
DirectoryEntry deGroup = new DirectoryEntry(results.Path, LDAPUser, LDAPPassword);
System.DirectoryServices.PropertyCollection pColl = deGroup.Properties;
int count = pColl["member"].Count;
for (int i = 0; i < count; i++)
{
string respath = results.Path;
string[] pathnavigate = respath.Split("CN".ToCharArray());
respath = pathnavigate[0];
string objpath = pColl["member"][i].ToString();
string path = respath + objpath;
DirectoryEntry user = new DirectoryEntry(path, LDAPUser, LDAPPassword);
ADUserDetail userobj = ADUserDetail.GetUser(user);
userlist.Add(userobj);
user.Close();
}
}
return userlist;
}
catch (Exception ex)
{
return userlist;
}
}

I have an application where I display every Active Directory group that the current user belongs to. When I have my config setup like this:
<authentication mode="Windows"/>
<authorization>
<deny users="?"/>
<allow users="*"/>
</authorization>
It works fine. When it's like this:
<authentication mode="Windows"/>
<authorization>
<!--<deny users="?"/>-->
<allow users="*"/>
</authorization>
No groups are found. Why does this make a difference? Does asp.net only authenticate if we are specifically denying access to unauthenticated users? If it helps this is how i'm getting the groups:
protected string GetUserGroups()
{
StringBuilder userGroups = new StringBuilder();
ArrayList groupMembers = new ArrayList();
DirectoryEntry root = new DirectoryEntry("LDAP://myldap/DC=nc,DC=local");
DirectorySearcher ds = new DirectorySearcher(root);
ds.Filter = String.Format("(&(samaccountname={0})(objectClass=person))", User.Identity.Name.Substring(User.Identity.Name.LastIndexOf(@"") + 1));
ds.PropertiesToLoad.Add("memberof");
try
{
foreach (SearchResult sr in ds.FindAll())
{
foreach (string str in sr.Properties["memberof"])
{
string str2 = str.Substring(str.IndexOf("=") + 1, str.IndexOf(",") - str.IndexOf("=") - 1);
groupMembers.Add(str2);
}
}
}
catch
{
//ignore if any properties found in AD
}
return String.Join("|", (string[])groupMembers.ToArray(typeof(string)));
}

We had few distribution groups in our AD for emailing. To provide access to my application i use these groups to generate the license keys.
Microsoft clearly says "Distribution groups play no role in security (you do not assign permissions to distribution groups), and you cannot use them to filter Group Policy settings."
Is there any way to get the token access for the Distribution groups?

I am using System.directory services namespace in framework 2 to query active directory. I have used fixed user account impersonisation in the web.config file, find the code:
<identity impersonate="true" userName="enterprise ang09" password="Telcome123"/>
<authentication mode="Windows"/>
I have disabled anonymous access in IIS. Also i have given Read & write access to the account tang09 for the website virtual directory and Microsoft.NET folder located in windows folder. But still i get prompted for the domain username and password to access the website.

Then later on, 2. Our server will upgrade to server 2003 to server 2008.
I would linke to know after doing above two phase will effect on Active Directory code setting in our program.
Can I conver to 1 to 1 withut changing anything in vb.net and server?

I am updating some CS code that was written in 2004, and that references some assemblies which extract user data from AD by query filtering on the user's title. I can't test my updated code in VS2010 because the assemblies no longer compile - the references are no longer valid (I can't create a DirectoryEntry or DirectorySearcher) so I need to work out how to replace the code with current directoryservices.accountmanagement namespace properties and methods. I have searched around but don't seem to be getting anywhere. give me some code that will work with vs 2010 to replicate the following:
