Changing the authschemes.xml File 

Use

You can change the file, authschemes.xml, with the config tool of SAP NetWeaver Application Server (AS) Java. Download the file to a local directory, edit it, and upload the edited file as a new node in the configuration tree. This way you do not lose the original version of the file.

Prerequisites

This procedure requires you to stop the AS Java, so you should plan for the required downtime while the AS Java restarts.

Procedure

...

       1.      Start the config tool.

       2.      Choose  with the quick info text Switch to configuration editor mode.

       3.      In the Display Configuration tab, choose cluster_config → system → custom_global → cfg → services → com.sap.security.core.ume.service → Persistent →authschemes.xml.

       4.      Choose  with the quick info text Switch between view and edit mode.

A warning appears for you to make sure the server and dispatcher nodes are shut down.

       5.      Choose Yes.

       6.      Choose  with the quick info text Edit the details of the selected node.

       7.      Choose Download and save the file to a local directory.

       8.      Edit the file locally.

       9.      Create a new node in the configuration tree for the edited file as follows:

                            a.      Select the node com.sap.security.core.ume.service.

                            b.      Choose  with the quick info text Create a node below the selected node.

                            c.      Select the type File-entry.

                            d.      Choose Upload and select the file from your local directory.

                            e.      Enter a name for the entry, for example, authschemes_productive.xml. By default, the system enters the name of the uploaded file.

                              f.      Choose Create.

                            g.      Choose Close window.

The new node appears in the configuration tree.

   10.      Change the value of the UME property login.authschemes.definition.file to the name of the new authschemes file.

Changing the value of this property requires you to restart the AS Java.
