Basic aspects of setting up an SAP Web Dispatcher with SSL
Throughout this new blog series, some basic aspects will be considered, as enumerated below:
- The SAP Web Dispatcher version.
The version used is the one recommended in SAP Note 908097 – SAP Web Dispatcher: Release, Installation, Patches, Documentation. Currently, I am using version 7.73, patch level 123, the latest available in the SAP ONE Support Launchpad.
As the scenarios are all SSL-related, note that the CommonCryptoLib is delivered with the SAP Web Dispatcher package. More on CommonCryptolib in SAP Note 1848999 – Central Note for CommonCryptoLib 8 (SAPCRYPTOLIB).
- The SSL configuration will be performed using the available UIs.
For the ERP/ECC system, STRUST will be used. Important: the test system used is based on the SAP NetWeaver 7.50 product. The interface is improved as of release 7.40. If you are using an older release (<7.40) and if you could not follow a step, then let me know using the comment section below; I will see whether I can find a similar (old) system and recreate the steps for such release. For the correct setup of SSL on the Application Server ABAP, SAP Note 510007 (Setting up SSL on Application Server ABAP) must be followed: read it carefully!
For the SAP Web Dispatcher, there is the Web Dispatcher Administration UI. Its menu brings the “SSL and Trust Configuration” item, with the “PSE Management”. More on this topic can be found in this wiki page.
The command line interface provided by sapgenpse will be only used as last resort.
- A special comment on STRUST.
Please, please, do NOT use the System PSE for SSL purposes. It will NOT work. The System PSE has no SSL purposes! If you are trying to use it, it means that you have NOT read SAP Note 510007: go back one step or game over.
- General troubleshooting information.
