Typically, EAM is configured to use a single service provider. The main reason to configure more than one service provider is if different IDPs are configured to return different SAML claims.
Two configuration files must be created for each service provider in <ssoclienthome>: sp*.xml and sp*-extended.xml.
The ensuing discussion will illustrate how to configure two service providers to control user access to production and test environments.
For the test service provider create files in <ssoclienthome> called sp-test.xml and sp-test-extended.xml.
For the prod service provider create files in <ssoclienthome> called sp-prod.xml and sp-prod-extended.xml.
