In this blog, I am going to explain how you could configure SAML SSO between wso2 identity server and was sample application snoop. You can find the port number of the was applications through the following the doc [1] and take the port number of WC_defaulthost_secure for the applications. Also please note that I have tested the SAML SSO configuration between wso2-is-5.7.0 and IBM WAS-8.0.0.12.
