I am using the data loader to upload and download data to and from Salesforce.com. However, we get the error of "(407) Proxy Authentication Required".

 

  For solutions, I have gone through the details in this forum, and find that we need to change the source to include "NTCredentials" in order to let the data loader support NTLM authentication. However, we find that that method "NTCredentials" is already included in the source.

 

  Could anyone inform me how to solve it? Further, from Apache client documentation, the authentication does not support some kinds of ISA server. Is it correct? Kindly correct me if I made any mistakes.

 

Regards,

Benny
