Better HTTP Authentication Support - Starting with NTLM

[James_McN]

As we increasingly integrate with HTTP servers the LabVIEW functions appear more and more limited.

Authentication is a major concern and in enterprise environments one option is NTLM (or Windows Authentication).

I would like to see the HTTP client support this as in this case we had to abandon using LabVIEW for the integration.

Is digest auth an option for you? IIS 6 (and presumably higher) supports digest auth to authenticate Windows users on active directory [1].

I believe LabVIEW's http client already implements NTLM on Windows (I.e. windows-client--to--windows-server) but I don't believe it works on Phar Lap, VxWorks, or Linux RT. Digest auth on the other hand is implemented (and tested) on all OS'.

Hi Haris,

Not in this case, the requirement for the system was to use Windows Authentication - LabVIEW was just looking to integrate with it.

I did give it a go on Windows but it did not seem to work. I could not find any documentation on what methods are supported - the help just points to the web service authentication pages so the assumption is that the open handle username and password is only for NI-Auth. If this is not the case this documentation should be updated.

Cheers,
James

I switched over from the NI HTTP toolkit to the secure TCP/IP funtions in the encryption compendium from LVS-tools. It's got basic and NTLM proxy authentication.
