Holy crab! :evil:
I think it has something to do with the slow connection.
We find a way to enable LDAP debug logging. Please download RC4 package again. You can find the log output in lsws/logs/stderr.log, pleae post it here.
Also, please do "ldapsearch -d 255 ..." and post the debug output as well.
Right now, you are the only one testing this feature. Hopefully, Paul, our another beta user, will get his hand on this soon. :-)
Thank you very much for your help!
