ISAPI module using IIS (7.5 under Win 2008 R2) having 32bit-support enabled.

[Stefan König]

Hello,

it took me about a week to resolve the following problem, which was 
quite enoying because there wasn't much debug information available.
Thus, I would appreciate if the support / developers would include a 
short hint 
(https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPWindowsIIS7Installer 
is the right place, thougth).
It could also be advantageous to adapt the Windows installer ...

Setup:
* Internet Information Services (IIS) 7.5 under Windows 2008 Server R2:
* 32-bit support enabled (IIS Manager => Application Pools => "Select 
Pool"=> Advanced Settings => Enable 32-Bit Applications: True)

Symptoms:
If configuring the 32bit ISAPI module OR the 64bit ISAPI module, it 
won't work. Having the 64bit-ISAPI installed the access to the 32bit 
Application isn't protected at all. Having the 32bit-ISAPI module 
installed I get a 500.0-Error message (maybe I mix up the symptoms of 
the 32bit/64bit-ISAPI module). Having disabled the 32-bit support the 
64bit ISAPI module works but the 32-bit application doesn't run...
I finally found that it only works, if I install both the 32 and the 
64bit ISAPI module in parallel with a *.sso-mapping for both...

Regards,
Stefan
