Hi,

My next step is to map a certificate to a user I selected in my datagridview.

I have following code to do so:

1    private void btnKoppel_Click(object sender, EventArgs e)
2    {
3        EIDCard card = new EIDCard();
4        card.InitReader();
5        array = card.ReadAuthenticationCertificate();
6        x509.Import(array);
7        //tbNaam.Text = x509.GetIssuerName().ToString();
8        
9        //create LDAP connection object
10       String pad = dgvGebruikers.SelectedCells[2].Value.ToString();
11       //MessageBox.Show(pad);
12     
13       DirectoryEntry entry = new DirectoryEntry(pad);
14       //DataSet userDS = new DataSet();
15       entry.Properties["userCert"].Clear();
16       //this step may be necessary depending on the
17       //version of .NET and ADSI that you have
18       entry.CommitChanges();
19       entry.Properties["userCert"].Add(x509.GetRawCertData());
20       entry.CommitChanges(); 
21       //DirectorySearcher search = new DirectorySearcher(myLdapConnection);
22       //search.Filter = "OU=Interne gebruikers Stad Kortrijk";
23       //int i = search.Filter.Length;
24   
25       //SearchResultCollection result = search.FindAll();
26       //cbGroep.DataSource = result;
27       card.DoneReader();
28       MessageBox.Show("Het certificaat werd normaal gezien gekoppeld aan de gebruiker!");
29   }

 Is there no one who has experience with this?

 Really could use the help :s
 

Maybe another question.

I have requested all the values of an entry object. To that entry a certificate has been manually mapped via the AD name mappings.

 
When I look at the list, I do not find a property with the name userCert or userCertificate.

This can't be correct.

A certificate is mapped to that account so he should find a property with that name.

Anybody knows the answer to this? 

I have solved the problem myself. Below is the solution:

1    private void btnKoppel_Click(object sender, EventArgs e)
2            {
3                //Instantiate an object of the type EIDCard
4                EIDCard card = new EIDCard();
5                //Prepare the card to be able to read from it
6                card.InitReader();
7                try
8                {
9                    //Get the lenght from the Authentication certificate so you're able to make your byte[] that large
10                   lengte = card.ReadAuthenticationCertificate().Length;
11                   
12                   arrayAuth = new Byte[lengte];
13                   //Read the authenticationCertificate from the card and put in a byte[]
14                   arrayAuth = card.ReadAuthenticationCertificate();
15   
16                   //Get the path of your DirectoryEntry.
17                   String pad = dgvGebruikers.SelectedCells[2].Value.ToString();
18   
19                   //create LDAP connection object
20                   DirectoryEntry entry = new DirectoryEntry(pad);
21   
22                   //Import the byte[] with the AuthenticationCertificate in your X5092Certificate
23                   x5092.Import(arrayAuth);
24                   if (checkIfCertificateHasBeenMappedBefore(x5092, entry))
25                   {
26                   }
27                   else
28                   {
29   
30                       //Get the format, name and issuerName from the certificate
31                       String format = x5092.GetFormat();
32                       String name = x5092.GetName();
33                       String issuerName = x5092.GetIssuerName();
34   
35                       //Strip the data from the certificate so the spaces behind the "," are removed
36                       String formatStripped = format.Replace(", ", ",");
37                       String nameStripped = name.Replace(", ", ",");
38                       String issuerNameStripped = issuerName.Replace(", ", ",");
39   
40                       //Put the stripped data in an object
41                       object altSecId = formatStripped + ":<I>" + issuerNameStripped + "&lt;S>" + nameStripped;
42   
43                       /*
44                        * Check if the property "altSecurityIdentities" is null.
45                        * If not, remove the current value of that property and commit your changes.
