I came across the situation where I need to implement SSO for Fiori launchpad. First thing came in my mind was to do through SAP NW portal since you can very easily achieve this by doing SSO between portal and Fiori. You need to configure SPNEGO on portal to make this entire thing work.
User open portal URL which redirected to Fiori launchpad. Issue with this you will have an additional portal page open which you don’t want any other users to see if you have published Fiori launchpad through your company portal or some other web page.
What tools required?
ADFS system in your organization
Fiori Gateway system
Certificate Signing Authority
How to achieve SSO through SAML?
Activation of SICF
First thing you need to login to SAP ABAP system/Gateway system where your Fiori Launchpad is opening from.
Go to transaction SICF and Activate SAML2 web service
Once you have this Service activated you will able to run SAP TCode: SAML2
