User Mapping (SAP Library - SAP NetWeaver Developer’s Guide)

User Mapping

User mapping is a feature that has been introduced to SAP products with EP 5.0. This feature provides log on information for users on third party systems. The log on information can simply be user ID and password and additionally information like NT-Domain and language.

In EP 5.0, user mapping is available as a personalization feature for every end user and as an administration feature that allows administrators to map users, groups or roles to specific accounts. In a productive environment, the user mapping feature contains a user interface to administer the data. In the SAP Enterprise Portal, the user interface calls the system landscape service to get a list of all systems that apply for user mapping. The system landscape has an user mapping attribute that has to be set accordingly.

The UME for EP 6.0 offers two interfaces to access the user mapping data:

· IUserMappingService

· IUserMappingData

Example:

import java.util.HashMap;
import java.util.Map;
import com.sap.security.api.IUser;
import com.sap.security.api.umap.IUserMappingData;
import com.sap.security.api.umap.NoLogonDataAvailableException;
import com.sapportals.portal.prt.component.AbstractPortalComponent;
import com.sapportals.portal.prt.component.IPortalComponentRequest;
import com.sapportals.portal.prt.component.IPortalComponentResponse;
import com.sapportals.portal.prt.runtime.PortalRuntime;
import com.sapportals.portal.prt.service.usermapping.IUserMappingService;

public class UserMapping extends AbstractPortalComponent
{
public void doContent(IPortalComponentRequest request,

                        IPortalComponentResponse response)
  {
   // obtain system
   String systemalias = "system";

   // get user from request
   IUser iuser = request.getUser ();

   // get usermapping service
   IUserMappingService iums = (IUserMappingService)
   PortalRuntime.getRuntimeResources().getService(IUserMappingService.KEY);
   IUserMappingData iumd = iums.getMappingData (systemalias, iuser);
   Map map = new HashMap ();
   try {
      iumd.enrich (map);
   }
     catch (NoLogonDataAvailableException nldae)   {
   // Error handling
   }

   // In m is all data
   String userid = (String)map.get( "user" );
   String pwd = (String)map.get ("mappedpassword");
   response.write("hallo"  + userid);
   response.write(" "     + pwd);
  }
}
