In order to accomplish what you'd like, you will need to SAML-enable not only abc.com but all the third party applications as well. Basic SAML Web SSO works under the assumption that each protected service communicates with the IdP.
In addition to what Chad said, you need to setup your shibboleth configuration file correctly for each application. (Mine is called shibboleth2.xml.) That configures your . NET application (I assume running under IIS with a certificate) to securely pass the logon values to the IdP for auth.
IIS should have the HTTP redirect set to MATCH the shibboleth configuration, probably https://abc.com/secure in your case.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
