[shib_auth] Page not found

[Markus Broman]

Hi

I'm trying to set up shibboleth(7.x-4.0-rc3) on a Drupal 7 site but I'm having problems.

When accessing https://example.com/Shibboleth.sso/Login I get "page not found". I have enabled DEBUG mode and there is no shibboleth attributes in the $_SERVER array.

I dont know if it has anything to do with it, but when dumping DEBUG message I get this error:

Notice: Undefined variable: _SESSION in shib_auth_debug() (line 176 of /var/www/drupal7/sites/all/modules/contrib/shib_auth/shib_auth.module).

Appreciate any help!
