Multiple MACs per Network

[Arran Cudbard-Bell]

John,

To be honest its probably easier to use SQL xlat then calling the SQL module if you're just trying to determine whether a mac address is allowed to access an SSID. SQL module is meant for more complex configurations. 

Create a new table with two fields 'ssid' and 'macaddress'

authorize {
	preprocess
	if(%{sql:SELECT COUNT(*) FROM `my_mac_table` WHERE macaddress = '%{Calling-Station-ID}' AND ssid = '%{Called-Station-SSID}'} >= 1}{
		ok
	}
	else{
		reject
	}
	rewrite_calling_station_id
	rewrite_called_station_id
}

FYI in your example you listed sql and sql.authorize, in the authorize section they do the same thing. Modules generally perform different actions depending in the section from which they're called adding a suffix of .<section_name> overrides this and explicitly sets a section name.
