Description

We are working with a hadoop system and trying to get the knox saml2 support working with our IDP. (note, this is not Okta but another IDP we use with many of our commercial clients internal and external.)

We have successfully configured knox 0.9.0 to handle the redirection to idp, we clearly see the assertion being passed back and being parsed by the pc4j component and the requestedurl being stored.

HOWEVER, it seems that when knox goes to retrieve this info, it finds a null.
(from last line of log snippet below) 2016-07-22 13:16:27,818 DEBUG session.KnoxSessionStore (KnoxSessionStore.java:get(90)) - Get from session: pac4jRequestedUrl = null

and therefore the final redirect seems to default to '/' instead of the actual requestedurl (in this case https://tchdpm01.lmig.com:8445/gateway/knoxsso2/webhdfs/v1/?op=LISTSTATUS)
