Ticket 47860 - register-ds-admin.pl problem when following steps to replicate o=netscaperoot
    
    Bug Description:  When following the documented steps the script gets stuck in
                      a loop when it fails to add "o=netscaperoot".  It's failing
                      because it already exists.
    
    Fix Description:  Break out of the loop when the update operation fails.
