Fiori back end user Synch with Front End and SAML SSO

Hi Everyone,

I am currently work in a Fiori Implementation project in which i need help and advise n the following things:

1. Synch of Back end users with front end System

We don't have CUA and Identity Management so i thought of doing a periodic Client refresh from the back end system with the Profile " SAP_UONL" to bring in all the users (only) to the front end system. Please tell me if this is Practically used or advised. If its okay, how shall i plan for the role assignment to the user users automatically

2. SSO config.

We used F5 as reverse proxy and the ADFS is used as IdP. So is there any document available to complete SSO using SAML for Fiori for these combinations of systems/tools

looking forward to your response

thanks,

Shi
