Motivation and Overview
After some time, I thought it is time to update the Document – SAP First Guidance – Implement SAP BW/4HANA in the Azure Cloud especially the topics for SAP Analytics Cloud and the SAP Analytic Cloud Connector which is necessary to overcome the Firewall Issues.
While I was configuring the SAP Cloud Connector (again on Azure Hyperscaler) there is a task – Configure a CA Certificate for Principal Propagation which I came to a interesting Side Note:
So: what is the (SAP) Secure Login Server (3.0) and what can it do for me?
Since I’m working since several Years with Azure Hyperscaler, my biggest Challenge was always to get a CA response for the server with the DNS *.azure.com. For SAP System which belongs to the *.sap.corp DNS we can create an own CA for these systems.
So I was trying to find a “transparent Solution” for this annoying issue and “Self-Signed” Certificates is not an Option for me at all, and that is the only suggestion you will get from SAP on many, many SAP Help Documentation.
In the End, I always ended by a Community Colleague Gregor Wolf (GitHub, Paasport – Gregor Wolf) who is one of the “real SAP Mentors” outside SAP. He let his mojo play on the systems and created the CA response based on let’s encrypt (honestly I never got the whole story so far … ;-))

Don’t be to astonished about the latest updates of the files. It seems especially here, you will see where SAP is shifted there invests: everything goes Cloud.
- pick only SECURE_LOGON_SERVER, SSOAUTHLIB and SSPEXTLIB SCA to avoid that the SUM process fails due to the already applied versions
- always finish a SUM update process properly, otherwise “reverting the system” might get complicated (no restore necessary)
- apply SAP JVM and UDDI patches first if needed.
- add the role SLAC_SUPERADMIN to your user.
