I would expect that OIDC will replace SAML based authentication over time.
Apache Fediz (since version 1.3.0) provides support for * SAML Web SSO * WS-Federation * OIDC
The great think about Fediz is, that is also supports a protocol bridge. So you can login with an IDP using SAML Web SSO and finally login to an OIDC Web Portal. https://cxf.apache.org/fediz.html http://janbernhardt.blogspot.de/2015/12/fediz-with-openid-connect-support-and.html
However SLO is currently not supported for OIDC. But since it is an open source project it should be simple to add this, as contributions are always welcome.
