We are still struggling with this problem. Some more facts we've discovered:
1. Problem happened only with 6-letter user names.
2. problem occurs somewhere between erlang port driver and python script. Our printout in erlang shows perfectly formed 'isuser' request, but python getting exception as described in original post.
3. The problem looks box specific, i.e some boxes have this problem even after re-installation of ejabberd,
other machines are fine.

Please, any ideas or suggestions!
Thanks,
-Igor.

It is impossible to fix the problem if the reason for the problem is unknown.

I don't know what is the reason of the problem. If you want to see what does ejabberd prepare to send, you can apply this patch to ejabberd 2.0.2 file extauth.erl, then compile and overwrite in your installed ejabberd. You can compile in Linux and copy the extauth.beam to your Windows machine. But I don't know if that will help you to find the problem.

You can check with a network sniffer (like Wireshark) that ejabberd really sends strange packet.

You can try a different extauth script, like the example Perl script.
