You are not supplying version number information for neither SP nor IdP. How

To debug signature canonicalization problems, you need the canonical
form from the sending end and see how it is different.
Basically you need to figure out from simpleSAMLphp documentation
how to make it print the canonicalization to a log and then compare
the canonicalization from the IdP end to the canonicalization from SP end (which
is available in the log message you quoted above).

Please do not thank in advance. Its rude and annoys me.

Consider subsrcibing to the list?
