Shibboleth Developers

[<>]

The attributes I am consuming on my SP are multi-line (base64 encoded, but with no constraint about whitespace, so they can include newlines).  With Apache and Shibboleth this is not an issue, but with IIS, I seem to only get the first line of the assertion. 

 

I know there is a work around by using exportAssertion and querying for the SAML assertion, then parsing out my attribute, but that feels non-optimal.  I am curious if the behavior I am seeing is correct or controllable in some way (perhaps an attribute decoder option to remove whitespace or more specifically newlines?).

 

I don’t have a 1.3 deployment that I can test against anymore, but I don’t recall this limitation being in the 1.3/IIS world (I know I did some testing in the 1.3 world regarding attribute size, but I might have done that testing with 0 whitespace, I don’t recall).
