I am trying to use Spring Security and SAML2 for SSO purpose.
We have an existing application based on spring web flow and spring security which uses db backed authentication mechanism (provider).
We are developing a new application which will not have its own authentication mechanism and will use authentication from 1st application.
I have downloaded the spring-security-saml2-core and sample apps from github, but i am unable to understand, what configuration and dependencies i need in the existing application to make it work like an idP.
I tried running the sample app using idP as ssocircle, but due to some corporate firewall issues, it doesn't work either.
Also, spring-security-saml2-sample app seems behave only as SP.
Can someone, point me in right direction to have my existing app configured as idP.
