Kerberos for Windows (kfw) and GSS-API in native 64 bit

[Julien Montmartin]

Hi List,

I'm working on an application server which will run on various flavour of
Windows and Unix OS, and need to support Integrated Windows Authentication
(IWA) to do SSO with Windows domain clients.

I've written some code that works on Linux, using GSS-API. Now I'm porting
this code on the Windows plateform. My first attempt was to get 'Kerberos
for Windows' kfw-3.2.2 sdk, and compile/link with it. It works well... in 32
bit mode !

That's where I need some help : my implementation must support linking in
native 64 bit. Dealing with 64 bit support, the kfw-3.2.2 release notes say
:

"Kerberos for Windows 3.2 is designed for 32-bit versions of Windows 2000,
XP, 2003, 2003 R2, Vista and WOW64 environments.  Native 64-bit Windows XP,
2003, and Vista applications are not being distributed as part of this
release."

As expected, WOW64 doesn't do the job for me, I really need native 64 bit.

- Are there any known issues with kfw in native 64 bit mode (which would
explain why it's not officially supported) ? Are there any plans to support
it in the near future ?

- Did any one manage to get it works in 64 bit by recompiling the sources ?

- Are there other solutions to get GSS-API on windows 64 bit plateform ? And
if not, any pointer to help me to port my GSS-API code to Microsoft SSPI ?

Thanks,

Julien
