LDAP Error:The directory service is not available

[pepe_gaetano]

Hi

I have a problem with LDAP, I use apache directory server and I would add a new user ....I use Visual Studio and the code

is:

public static void prova(string FullName)
        {          
            DirectoryEntry container;
            DirectoryEntries ChildEntry;

            container = new DirectoryEntry("LDAP://localhost:10389/cn=user1,ou=users,ou=system", "admin", "secret");

            try
            {

                ChildEntry = container.Children;
                DirectoryEntry NewEntry = ChildEntry.Add("cn=" + FullName, "user");
                NewEntry.CommitChanges();
                NewEntry.Close();
            }
            catch (Exception ex)
            {
                throw new Exception("Error " + ex.Message);
            }
         }

The problem is that I have this type of error:The directory service is not available
somebody could help me?

Hi,

I believe you need to use the full DN of the user in your DirectoryEntry creation.

Maybe the following code would work better...

DirectoryEntry("LDAP://localhost:10389/cn=user1,ou=users,ou=system", 

"uid=admin,ou=system", "secret");

Hope this helps,

Pierre-Arnaud

I tried with "uid = admin, ou = system" but I have always the same error

[Stefan Seelmann-3]

Hi,

And you are sure that ApacheDS runs on your machine on port 10389?

Could you try to get a more details error message?

Could you find out which line of your code causes the error?

A last advice is to use capture the network traffic, for example using
Wireshark (but afaik it is not possible to capture the localhost
interface on Windows).

Kind Regards,
Stefan

the server and port I think they work because I checked using Apache Studio! the error is here
newentry = ChildEntry.Add DirectoryEntry ( "cn =" + FullName, "user");

Is "cn=user1, ou=users,ou=system" really your container or do you want
to add new entries to "ou=users,ou=system"?

To do a simple bind you need to use a bind DN and specify the right
authentication type (AuthenticationTypes.None). I'm not sure if other
authentication types work with non-AD servers.

Apache Directory Server doesn't contain the "user" object class. So if
you haven't added it to the schema you should use another object class
(e.g. inetOrgPerson)

Before you commit the changes you need to add all the other mandatory
attributes (cn and sn for inetOrgPerson).

Here is your modified code that works for me:

try
{
    DirectoryEntry Container = new DirectoryEntry(
        "LDAP://192.168.2.101:10389/ou=users,ou=system",
        "uid=admin,ou=system", "secret", AuthenticationTypes.None);

    DirectoryEntries ChildEntries = Container.Children;
    DirectoryEntry NewEntry = ChildEntries.Add(
        "cn=" + FullName, "inetOrgPerson");
    NewEntry.Properties["cn"].Add(FullName);
    NewEntry.Properties["sn"].Add(FullName);

    NewEntry.CommitChanges();
    NewEntry.Close();
}
catch (Exception ex)
{
    Console.Out.WriteLine(ex.Message);
    Console.Out.WriteLine(ex.StackTrace);
}


BTW: There is a much better C# LDAP API from Novell, see [1][2]. There
are also many examples available.


Kind Regards,
Stefan

Hi Pepe,

use groupOfNames or groupOfUniqueNames.

I'd kindly recommend to study some LDAP book first in order to learn the
LDAP basics. A nice online book is http://www.zytrax.com/books/ldap/

Kind Regards,
Stefan
