Shibboleth sp and mod_wsgi on the same Apache-2.4 server

[Jörg Knappen]

I am running shibboleth-sp-2.5.3 on Apache httpd-2.4.7. I use a  
"defensive" configuration
with

ShibDisable On

for all non-protected parts of the server.

Now I tried to integrate a non-protected Python application with  
mod_wsgi and got the error:

Access denied. [...] Error 403

The same Python application runs without problems on the same server  
when I integrate it with mod_fcgid.

The same Python application runs without problems on a (otherwise  
same*) server without
Shibboleth.

Anyone encountered a problem like this before?
