Szenario A trust between the SAML 2.0 IdP and SP is created. A user tries to log on to NetWeaver and after successfully logging in at the IdP, the SP is denying access. Problem Using the diag tool to get a trace of the SAML 2.0 logon. The incoming request Read more…
In the SAML 2.0 SSO logon with automatic user creation scenario, the user is created in the SAP system by a BADI. The user information send by the SAML 2.0 IdP is contained in the SAML response. In my previous blog I have shown how the user profile is configured Read more…
The user creation scenario is an extension to the “simple” SAML 2.0 SSO scenario. Therefore, a pre-requisite is to have the SAML 2.0 IdP and SP configured to trust each other. A logon from IdP to SP with an existing user must work. In my case, the external Identity Provider Read more…
The ICF configuration is more complex than the standard SAML 2.0 configuration. Instead of just validating the SAML 2.0 response, the response must be validated, and a user created or update. To be able to create / update a user, the response received must be handled by a service user. Read more…
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…
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…
