Hi, a somewhat sophisticated problem: in a mail server, we'd like to record the IP address of the client that triggered the IMAP authentication request. The IMAP server uses PAM, specifically pam_radius_auth. Is there a way to tell pam_radius_auth to send a value in Calling-Station-Id? Is there a way at all to send variables to PAM at all, to be used for setting Calling-Station-Id within pam_radius_auth? We could also live with getting the value into PAM and then setting it into client_id= if Calling-Station-Id is not possible; string mangling on the server side would do nicely. Something like client_id=@{SOME_STRANGE_PAM_ITEM_WHICH_CONTAINS_MY_DESIRED_VALUE} as an option to pam_radius_auth?
