Shibboleth 2 interoperability. This is acchieved by increasing the

storage for attributes, as OID-named attributes sent by the Shibboleth

There is also a required Destination attribute in AuthnRequest elements.
It is done by trunk version of lasso, but not by any currently released
version, hence we do if it is not done.
