single sign on - Shibboleth SP to point to multiple idP -

I have SP installed on a machine. Based on URL, I have to configure on several IDPs.

Ex Our two hosts one.myorg.com and two.myorg.com are the same modules / machines - the same SP.

Now I need to configure my SP as if it is one.myorg.com/secure , for the SP to authenticate https://testshib.com / Idp and the other will be two .myorg.com / secure , go to SP on https://myown.idp.com needed.

EDIT: IDP should not ask for it to choose.

If it is still real, then you can find some hints here. / Del> Shibolt on Wiki

The main idea is to provide an IDID to the IDP in a manually created login request for the SP login module, such as

  Https: //sptoestshib .org / Shibboleth.sso / TestShib? EntityID = https% 3A% 2F% 2Fidp.testshib.org% 2Fidp% 2Fshibboleth  

Where entityID = ... IDP's url-encoded unit is IDI in question.

The documentation for this parameter can be found in the "Advanced Configuration" section.
