Shibboleth SP - Http/1.1 Service Unavailable

[frederic.jean at orange.com]

Hello,

I'm trying to get a php application to use shibboleth SP for authentication.

I have installed Shibboleth SP (2.5) on the apche http server.

It is configured to work my my IdP.

I have configured a fake "/secure" URL which required shibboleth authentication.

When I call the URL, I get properly redirected to the IdP, I then authenticate and get redirected to my URL and thus get a 404 error, which is the expected behavior because the page does not exist.

Now if I just change the configuration to protect not just that dummy test URL but the actual application, I then get an "Http/1.1 Service Unavailable" when I try to connect to the application (I don't even get redirected to the IdP). When apache is not configured to require shibboleth authentication, the application works properly, it does not yet include the code to use the attribute provided by shibboleth sp, so I would expect no change in the application behavior when protected by shibboleth SP.



Here's my apache shibboleth config :

<Location />

  AuthType shibboleth

  Require shibboleth

  #mode lazy session

  ShibRequestSetting requireSession 0

#  ShibRequestSetting requireSession 1

#  ShibRequestSetting applicationId default

#  require valid-user



#  require shibboleth

  ShibUseHeaders Off

</Location>



<Location /secure>

  AuthType shibboleth

  ShibRequestSetting requireSession 1

  ShibRequestSetting applicationId default

  require valid-user

  ShibUseHeaders Off

</Location>



The problem occurs if I change /secure by /medecin (the actual application path) or if I try to enable requireSession on /

I can't see anything in the logs to explain this issue.



Does anybody know what could lead to this behavior ?



Thank you.



Frederic JEAN
