Assign user Tasks to another (user will be deleted)

Username renaming is not directly possible by an (official) public API, but:

• If the Security System is connected with an External Security System (i.e. AD), a renaming of the external security name OR the user name is supported. Except, both are changed at the same time.
• If the Security System is not connected to an External Security System, you could rename the user name in the IWA_User system database table (after stopping the Axon.ivy Engine).
• Or, as a workaround, the Interface IUser could be casted to User, and then the method setName(..) is available. But the method has to be executed as system.

Code example:

package wf;

import java.util.concurrent.Callable;

import ch.ivyteam.ivy.security.IUser;
import ch.ivyteam.ivy.security.internal.User;
import ch.ivyteam.ivy.server.ServerFactory;

public final class WorkflowAdminUtil {
    private WorkflowAdminUtil(){}
    public static void setUserName(IUser user, String newUserName) throws Exception {
        ServerFactory.getServer().getSecurityManager().executeAsSystem(
            new Callable<Void>() {
                @Override
                public Void call() throws Exception {
                    ((User) user).setName(newUserName);
                    return null;
                }
        });
    }
}
