Actually you are right. I investigated this further today and I
realized it was neither pysaml2 or simpleSAMLphp bug, it was a bug in

I was logging in simpleSAMLphp using an authentication mechanism
different from the one used when simpleSAMLphp is acting as an IdP and
hence there were two sessions involved.

Sorry for the noise. This bug is invalid.
