Configurate roles in CUPS 1.3.7

[Jim]

Hello,
I'm starting with CUPS 1.3.7 configuration and can't see any option to create or modify roles into cupsd.conf file.
I'm modifying the configuration file (cupsd.conf ) but I can't separate roles into Web Service Administration site (http://<localhost>:631). I'd like to know if this is possible to create a role only for administrator whom can do administrator tasks (create printer, clases, etc) and another role with operation roles (stop and start printers, cancel jobs,etc).
I've created some groups, but it didn't work.
Please, let me know if this is possible with CUPS 1.3.7 or I have to migrate to newest version.
This is part of my configuration file:

LogLevel info
