 In radcheck table, if we use email address as value in User-Name
attribute, user can login with his email address as username. In case if we
use MAC as value in User-Name attiribute, user can login using MAC
authentication. As of now, we can use 'only' either value. Requirement is
to enable user to use both. He can login with either email or MAC. Just
found the below solution suggested in one of the forum. Would like to know
if it is feasible?

1 - open this path
2 - search in : authorize_check_query
reblase all query to :

authorize_check_query = "SELECT id, username, attribute, value, op, mac \
FROM ${authcheck_table} \
WHERE username = '%{SQL-User-Name}' and (mac IS NULL or
mac='%{Calling-Station-Id}') \
3 - add new colum `mac` in database in `radcheck` table and set him to
4 - add your current user with the password with the two or three mac's
as you want.
