We are trying to integrate a PL IDP with a vendor SP that we don't have any control over. Their SP is rejecting our response assertion because it includes 2 AttributeStatement blocks and they are expecting 1.
While the spec at http://docs.oasis-open.org/security/saml/v2.0/saml-core-2.0-os.pdf on line 2077 seems to indicate that multiple AttributeStatements are a technically correct approach, I'm not sure it is a "normal" approach. I know simplesamlphp IDP doesn't do multiple AttributeStatements out of the box. If you happen to know that other IDPs take the multiple AttributeStatements approach feel free to close this ticket. If you aren't sure, please decide if you think PL should be changed to issue a single AttributeStatement instead of multiple so it can be technically correct and potentially more "normal" so that we would have better compatibility with 3rd party SPs.
We have now had 2 vendors complain about this. The 2nd one was savvy enough to patch the pysaml2 library they were using https://github.com/BetterWorks/pysaml2/commit/64a2078aa19535cc8825282a4e16353c4448303b?w=1. This however does confirm in my mind that what we are doing isn't "normal" and needs to be changed.
