I am trying to configure Websphere 8.5.5 with a SAML SSO. I am following the article http://www.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/twbs_configuresamlssopartners.html.
The step 1 was done with "Add an identity provider using metadata of the identity provider."
I got stuck at step 2c. what's the external realm should I use? I assume it's the external idp realm. But where to find the name for it?
