Using Spring SAML as an IDP rather than an SP

Question

Are you able to use Spring SAML if you are implementing as an IDP?

I have used it in the past when acting as a Service Provider, and having read the documentation its not clear on whether I can use it as an IDP.

Note - I originally asked for opinions on another question which was put on hold by Users, I reworded the question as above but its still on hold hence I have asked again.

Answer 1

There's no support for acting as an IDP in Spring SAML. Capabilities of Spring SAML are described in the manual:

"The extension enables both new and existing applications to act as a Service Provider in federations based on Web Single Sign-On and Single Logout profiles of SAML 2.0 protocol."

For implementing SAML 2.0 IDP using open source tools have a look at for example Shibboleth.
