 I am experiencing this problem as well.  The issue *can* be resolved by
 turning off NTLM authentication on the server; however, this is not an
 option available to me.

 From the trace above (I am getting an identical trace), the problem
 appears to be a failure in the NTML challenge/response authentication
 sequence (http://www.innovation.ch/personal/ronald/ntlm.html).  Curiously,
 it only happens on uploads - all other operations (that also require such
 a sequence) complete successfully - this can be easily observed by tracing
 those operations.  For whatever reason, the response that Cyberduck send
 to the server once the server requests NTML authentication (during the
 upload operation) is greeted with "Bad Request".

 My server is Microsoft-IIS/6.0.  This issues is preventing me from using
 Cyberduck, which is otherwise a very nice tool!
