Hi Vijay, Currently there are no community-supported SAML login identity providers. You can use the existing LDAP [1], Kerberos [2], and OIDC [3] implementations as examples on which to base your implementation. The LIP are not currently exposed as a first-class extension point, but you can certainly build a custom one and use it locally, even without submitting it for inclusion in the core project. Of course, this sounds like a valuable feature for the community, and we encourage contribution if possible.
We are open to rearchitecting the authentication and authorization mechanisms in NiFi, but cannot make breaking changes that would change backward compatibility on minor version releases because we follow semantic versioning [4]. Changes which alter the fundamental authentication story NiFi presents need to go in a major release (i.e. 2.0.0). NiFi strongly adheres to stable releases which follow the principle of least surprise. If you have specific questions or need help with integrating the code, please feel free to reach out to the community here or on GitHub. You may also be interested in the developer mailing list at d...@nifi.apache.org <mailto:d...@nifi.apache.org> for more code-related questions and discussion. Thanks.
