SAP Help In the previous blog I detailed the BADI provided by SAP for creating and updating a user that logs on via SAML 2.0 and what to take care of. In this blog I’ll detail how to implement the BADI. The implementation means that some ABAP coding is needed. Read more…
The BADI you have to extend to be able to create or update a user in the SAP NW system based on the SAML 2.0 information is BADI_SAML20_USER_CREATE_UPDATE. It offers two methods, one for creating a new user, one for updating an existing user. Keep in mind that the SAP Read more…
SAP decided to end SAP Cloud Platform (SCP) Neo trial some time ago and now also communicated the date when they will plug the plug: 13th November 2020. SAP announced long ago that they are investing in the SCP cloud foundry stack (SCP CF), and that Neo is out of Read more…
Assume that you use SAP WebIDE for developing an application and that you have to consume an OData service from an on-premise NetWeaver ABAP system. In SCP, the destination is configured, and SAP Cloud Connector is working. For principal propagation, X.509 is used. Problem When you select the OData service Read more…
SSO logon with an X.509 certificate offers some benefits. In this blog, I’ll cover the main benefits, problems and attention areas when using X.509 for SSO. As a practical example the X.509 logon with NetWeaver ABAP is shown. To access an ICM service on a NetWeaver ABAP system (NW ABAP), Read more…
ICM in NetWeaver ABAP is not reading the HTTP header and accepting the transmitted X.509 certificate simply like that. I’ll show here a picture that shows what an intermediate server is sending to NetWeaver. You can see that two certificates are transmitted to SAP: the user X.509 as well as Read more…
In many cases a proxy is placed between the end user and the SAP backend, like a Web Dispatcher. User –> Proxy (intermediate) –> SAP The proxy / intermediate receives the user certificate, extracts and adds it to HTTP header SSL_CLIENT_CERT. When a connection to the SAP backend is opened, Read more…
After configuring your NW ABAP instance to support user logons with X.509 certificates, it is time to test the correct setup. The test is simple: access a HTTP service like Web Gui and log on by sending a user certificate. Activate SAP Web Gui service Tx: SICF Select webgui and Read more…
For this configuration step, the same pre-requisites as for 4.2 apply. This option is like a technical user with X.509. The logon is done with a X.509 certificate, and a fix SAP user is assigned. That is, your user will always log on with the same user id in SAP, Read more…
Besides mapping a X.509 user to a given user ID in an SAP system, you can also map the user by an alias or to a specific user. In step 4.3 I’ll show the configuration for alias mapping, and in 4.4 for a specific user. Create alias for user Tx: Read more…
