I tried using the rewrite.called_station_id module from policy.conf and whilst it does not error it doesn't rewrite the incoming Called-Station-Id to the format I require.
My NAS always send in the correct format, however I have set rewrite.called_station_id at the very first in authorize {} because it should be the first thing to be done. I could sanitize it just when sending it to LDAP but then Radius would always use the wrong format. That is why you don't want to sanitize it just in the SQL query. What you should do is modifying the regex used in the rewrite.called_station_id policy to also match 001122334455 formats. In authorize at least &Called-Station-Id is available, probably also %{Called-Station-Id}. There is a nice regex tester at http://www.freeformatter.com/regex-tester.html The default regex used is ^([0-9a-f]{2})[^0-9a-f]?([0-9a-f]{2})[^0-9a-f]?([0-9a-f]{2})[^0-9a-f]?([0-9a-f]{2})[^0-9a-f]?([0-9a-f]{2})[^0-9a-f]?([0-9a-f]{2})([^0-9a-f](.+))?$ and this matches 00-11-22-33-44-55 and 00:11:22:33:44:55 and 001122334455 as well as other formats.
