It also looks like it is missing some dependencies.
In short, I'm trying to use shibboleth without apache (via nginx), but the 
backported package assumes that apache2 is installed (thus a2enmod available).
Installation then fails as follow:

> apt-get install -t wheezy-backports shibboleth-sp2-common
> shibboleth-sp2-utils libshibsp6 liblog4shib1 libsaml8
> opensaml2-schemas libshibsp-plugins

I'm raising the severity of this, since the backported package is currently 
unusable in this case, due to the hard-coupled implicit dependency on Apache.

Russ, can you please revert/modify your a2enmod changes for the ~bpo revision?

I'd like to use the daemon part of shibboleth-sp2-utils in a standalone way,
and vanilla package from jessie seems to be better in that regard.

Cheers, Luca
