SpringBoot - Enabling Neo container Authentication

Hello ,

We have current applications running on Neo that are servlet based applications. While we do plan to move to CF and have applications already on CF , we are trying to work with SpringBoot on Neo. One of the problems that we faced is as described in the Stack Overflow Question here java - How to perform SAML authentication with Spring and SAP Cloud Platform - Stack Overflow.
In the JAX-RS based application we have the security working, how to acheive the same with SpringBoot we have tried multiple things with no success!
Please note that we are looking for this to work on Neo and not just move to CF and use XSUAA.

Any pointers would help thanks!

Regards,

Joshua
