A free, open source authentication provider for DNN.

You can now Single Sign On from a remote website (if it has implemented SAML) to your DNN Portal.

SAML
https://en.wikipedia.org/wiki/Security_Assertion_Markup_Language
Security Assertion Markup Language (SAML) is an open standard for exchanging authentication and authorization data between parties, in particular, between an identity provider and a service provider. SAML is an XML-based markup language for security assertions (statements that service providers use to make access-control decisions). SAML is also:

• A set of XML-based protocol messages
• A set of protocol message bindings
• A set of profiles (utilizing all of the above)

The single most important use case that SAML addresses is web browser single sign-on (SSO). Single sign-on is relatively easy to accomplish within a security domain (using cookies, for example) but extending SSO across security domains is more difficult and resulted in the proliferation of non-interoperable proprietary technologies. The SAML Web Browser SSO profile was specified and standardized to promote interoperability.

https://en.wikipedia.org/wiki/Identity_provider_(SAML)
A SAML identity provider is a system entity that issues authentication assertions in conjunction with a single sign-on (SSO) profile of the Security Assertion Markup Language (SAML).

In the SAML domain model, a SAML authority is any system entity that issues SAML assertions.[OS 1] Two important examples of SAML authorities are the authentication authority and the attribute authority.
