Hi,
I've get configured our NW Gateway system (NW 7.31) with external identity provider by SAML2, so our web apps (web dynpro and SAPUI5) are now accessible for people who don't have account in our SAP system, but have access to our other system (nonSAP). My question is how to read user name of this user authenticated and authorized on external server in ABAP code of our web apps?
Many thanks for answer Jiri.
