 
      In some cases SRM transfers fail because they are tried via
      the plain dCap protocol (URL starts with
      dcap://). Since plain dCap is
      unauthenticated, the dCache server will have no information
      about the user trying to access the system. While the transfer
      will succeed if the UNIX file permissions allow access to
      anybody (e.g. mode 777), it will fail otherwise.
    
      Usually all doors are registered in SRM as potential access
      points for dCache. During a protocol negotiation the SRM
      chooses one of the available doors. You can force srmcp
      to use the GSIdCap protocol
      (-protocol=gsidcap) or you can unregister
      plain, unauthenticated dCap from known protocols: From the
      file config/door.batch remove
      -loginBroker=LoginBroker and restart
      dCap door
[root] #jobs/door stop[root] #jobs/door -logfile=<dCacheLocation>/log/door.log start
