Multiple IdPs problem

The documentation is modified in order to allow mulitple
IdPs using the OS-Federation avoiding conflicts among them.

The previous proposed configuration allows user from one IdP
to get mapped as user from a different IdP. With the chenge
proposed this is not anymore possible.
