how to make use of an username parameter in an initial POST request

Hello folks,

  we have office365 set up to use our shibboleth IdP. In Office365 users 
have to write username in a login form and are redirected to institution 
login page. In this initial POST request following paraneters are set:

- RelayState
- SAMLRequest
- username

Of course, by the time login page is shown (one redirection later), 
those parameters are not available to login.vm view. Is there any way to 
access initial POST parameters from loginpage? Is it possible to store 
that parameter in some session variable?

It would be very convenient for users not to be forced write usenames twice.

Our shibboleth IdP version is 3.4.4

Thanks for any ideas.
