I have SP installed on a machine. I need to have it configured to multiple idP depending upon the url.
Ex.
We have two hosts one.myorg.com and two.myorg.com both point to same module/machine - so same SP.
Now I need my sp configured as if one.myorg.com/secure is hit SP should go to https://testshib.com/idp for authentication and else two.myorg.com/secure is hit SP should go to https://myown.idp.com idp.
EDIT: It should not ask to choose the idP.
In case this is still actual, you can find some hints here: https://wiki.shibboleth.net/confluence/display/SHIB2/IdPDiscovery. on the Shibboleth Wiki here.
The key idea is to provide a entityID to the IdP in question in a manually crafted login request to the SP login module, like
https://sp.testshib.org/Shibboleth.sso/TestShib?entityID=https%3A%2F%2Fidp.testshib.org%2Fidp%2Fshibboleth
where entityID=... is the url-encoded entityID of the IdP in question.
The documentation of this parameter can be found on the Shibboleth Wiki in the "Advanced configuration" section.
