You didn't review the metadata before you plugged it blindly into the SP.  This is a pretty insecure thing to be doing.  If this is
a test instance you should be learning from it and in production there are security implications (and I have been caught in the same
trap so: "hi kettle, my name is pot").

The metadata the IdP generated has a validity date in it of "now".  Review you metadata edit and redeploy it
