What exact attribute name and nameformat does the SP expect?
Probably that's simply something else than what your IDP is sending?

Well, what the IDP is sending on the wire will look like
<Attribute xmlns="urn:oasis:names:tc:SAML:2.0:assertion" FriendlyName="mail" Name="urn:oid:0.9.2342.19200300.100.1.3" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri">
<AttributeValue>peter.schober at univie.ac.at</AttributeValue>
so those exact data points (name, nameformat) is what the SP would
need to be looking for.

There there's no reason to doubt that your IDP is sending it.

As with other forms of "but it doesn't work": Sadly that's not a
technical error report that would allow anyone to help you diagnose

You'll need to find out how to make the SP look at the concrete data
your IDP sent.
Or otherwise find out how to make your IDP send the concrete data that
the SP expects, if and only if the SP cannot be configured to look at
the concrete data your IDP sends.
