There is a policy "rewrite_calling_station_id" which nearly does that 
already - see raddb/policies.d/canonicalization

Copy that to e.g. rewrite_user_name_mac and change it to use User-Name, 
and to use ':'s instead of '-'s, then call it from your authorize{} section.

If you don't want to change User-Name, add your own attribute to 
raddb/dictionary and alter the update to use that instead.
