[rules-users] guvnor - role based auth enabled - cannot use backup URL anymore

All, I am using drools5 guvnor, and I have enabled the role based permissions. I have been using wget and this URL to get repository backups - http://localhost:4980/guvnor/org.drools.guvnor.Guvnor/backup <http://localhost:4980/guvnor/org.drools.guvnor.Guvnor/backup> Once I enabled role based permissions, I when I use the backup URL, I get a http response code of 500. In a browser, the backup URL produces the 500 response with the message that the user is not logged in. How can I use the backup URL with role based permissions enabled? I can find something other than wget, but I don't know how to specify the authorization credentials with the request or remove the access restrictions on the URL. Does anyone know how to do this? Thanks, John
