I had a great idea for a little app to synchronise my personal LDAP server with my BB (on BIS) contact list. I know C#, and sit next to a knowledgeable java guy at work, so thought I would give it a try.

So, I've got myself an app set up using the JDE 4.7 beta, and the first thing I thought to try was to connect to my LDAP over the internet using the net.rim.device.api.ldap namespace. I simply try to do an anonymous bind and then fetch all the entries for a particular base DN. Here's my code:

Java pastebin - collaborative debugging tool

I've highlighted the section that makes the LDAP connection. I've fixed the hostname / querytype rather than read it from the form to make troubleshooting a little easier.

When I run it in the simulator (9530) it comes up with "Success: 0", meaning that it thinks the query was successful and it found 0 records. The problem is, running my LDAP server in debug mode shows that it doesn't even connect to the LDAP server, and there definately are records behind that DN.

So, has anyone had this sort of trouble before? Annoyingly, I can't test it on a real device until RIM gives me some code signing keys.

Anyone?

I've tried doing a connection to a public LDAP server to request what should be about 114 records. Still no beans. Here's the code:

your implementation of LDAP is more or less similar to my test application. first, i tried implementing it using the LDAP_AUTH_ANONYMOUS, but it never seemed to work and i read in some forums that there is a problem with the anonymous authentication with regards to the server security and stuff. so i tried changing the authentication from anonymous to simple, and it worked.

try changing your authentication from LDAP_AUTH_ANONYMOUS to LDAP_AUTH_SIMPLE. maybe this is the reason why it won't work. just give it a try.

I'll indeed give that a go and report back!

When I run it in the simulator (9530) it comes up with "Success: 0".
The same thing as this thread meant for.

Do anybody have any suggestion/solution?

[baskaraninfo]

Initially it is asking for the user credentials, when we provide the user credentials it is showing the same error, "Success: 0", irrespective of the valid or invalid user details. Any help?

I think we're taking it for granted that the simulator is completely broken. However, it seems that only anonymous auth is broken on the device and that credentials might work. Did you test only on the simulator?

[baskaraninfo]

Thanks growse..

Yes, presently am only testing using the Simulator [Version 9530]. For anonymous and as well as with user credentials the results are seems to be the same.

I doubt whether it is actually tries connect to the LDAP or not.
