Hello Heikki, As per my previous e-mail below, is it possible instead to pass the password I received from the external API as stated on item [1] to the built-in "processor" that the Radiator has instead of performing the item[2], then let Radiator do the rest? Meaning, my script will just fetch the password from an external API for Radiator to process it and let Radiator do the rest of the remaining processes. Please advice. Thank you.

Since in my case that I am getting the password from an external API via an AuthBy EXTERNAL script, does it mean that I have to do the following step s below upon receiving the user's Access-Request? [1] The external script will query the external API server and get the user's password; [2] The script will then convert the password received into a CHAP-Password format (e.g. CHAP ID + MD5SUM of CHAP ID + password + CHAP-Challenge); [3] Compare the CHAP-Password received from the user's Access-Request vs the CHAP-Password that was converted as per item [2]; [4] Whatever the result of item [3], my script will then do an "exit 0" or "exit 1". Please advice. Thank you very much. _______________________________________________ radiator mailing list [email protected] http://www.open.com.au/mailman/listinfo/radiator
