Hi Michael,

[...]

Native code is not something that will work for ManifoldCF because it must
work the same on linux as well as windows systems.  So SSPI cannot be a
replacement for the proprietary NTLM implementation at this time.

As for Kerberos -- we have people who use it, although with difficulty.

It shouldn't if done right.

What we're really missing is a non-native Java way of obtaining Kerberos
tickets given the appropriate credentials, before it can hope to replace
NTLM.  This is because authentication is built into MCF connectors; it must
be possible to authenticate within the application.

Obtaining a TGT from within Java with a UPN and a password is a snap and can be done with a few line of code. After that, you have a GSSCredential and are good to go. No magic here. Maybe I need to understand your usecase better.

Welcome onboard!

I'm the lead with the ManifoldCF project, which is a heavy user of
httpclient, and the implementer of the NTLM code that HttpClient currently
includes.  I'm looking forward to someone keeping up to date with all the
various authentication/authorization protocols, since this changes
apparently hourly these days.


NTLM is a proprietary and tricky beast. Avoid it, if you can, migrate to
Kerberos.

As for auth, I will focus on GSS-API-provided mechs first and those from
SSPI (which supports NTLM natively) then I will take a look at the
proprietary stuff.

Please keep an eye on my changes and test it once in a while. Give
feedback if necessary.


Michael
