BlackBerry user authentication with LDAP

After I've tried so much and still being stuck, I hope anyone here has an idea. Well, that's the situation: I'm trying to login to my app with ldap. If its possible to login there, you can go on using the app.

I've already tried to use net.rim.device.api.ldap.LDAPQuery but the problem is, that if I try to log in, the LDAP Login Screen overlays my Login Screen and I have to enter my username and password again. Besides, if I enter nonsene into that form or cancel the login I also get logged in. By the way, why can't I set my password with LDAPQuery ? I just send my username to the directory. That's not what I feel about security.

Adding a 3rd party jar files to use LDAP was another negative attempt. I also couldn't get them preverified. And I thi开发者_Go百科nk that's the main reason why they're not working.

Here are some information about my development environment: I'm using eclipse with the BlackBerry java Plug-in and BlackBerry Java SDK 5.

Ok, if you have any ideas on that or which alternative library I could use, please let me know !

Is your device connected to a BES server (via MDS)? From what I understand, the native LDAP client libraries in the BlackBerry API only work as an interface to a MDS (Mobile Data Service) LDAP component which does the actual work.

If not, then you'll need to find a third-party LDAP library that works on BlackBerry/J2ME. I have seen this question asked before but have yet to hear about a third-party LDAP library.

From what I can tell the LDAPQuery class in the RIM API does not work. Please let me know if this is incorrect.
