Message decoding error

[Wessel, Keith]

Ah, that makes sense that one would zip the redirect binding parameters. Thanks for that clarification.

No, not OpenJDK. Oracle Java 8 update 74.

Tom, I'd be happy to post the SAML authn request if I can get it. Turning upt he OpenSAML logging to DEBUG didn't seem to log it. Will I need to grab it with an SAML trace, or is there a way to make the IDP log it?

The SAML Redirect binding is an unsigned XML document run through a DEFLATE and then URL encoded. ZIP is basically DEFLATE plus an additional bit of padding, so inflating it is done with the Java zip stream class.

Well, you can always run the message through FEIDE's SAML debugger that decodes redirect messages, but I'm not aware of any real interop problems of that trivial a nature.

Don't suppose this is OpenJDK?
