Freeradius ships with a dictionary file named dictionary.unix, that contains the following attributes: VENDOR Unix 4 BEGIN-VENDOR Unix ATTRIBUTE Unix-FTP-UID 10 integer ATTRIBUTE Unix-FTP-GID 11 integer ATTRIBUTE Unix-FTP-Home 12 string ATTRIBUTE Unix-FTP-Shell 13 string ATTRIBUTE Unix-FTP-Group-Names 14 string ATTRIBUTE Unix-FTP-Group-Ids 15 string END-VENDOR Unix Is the goal of this set of attributes to enable a Radius server to send back UID, GID, etc. information for a user that has been authenticated by the RADIUS server? If so, why use FTP in the name of the attributes? I mean, a Radius server will not be able to know whether the users being authenticated is accessing the target system via FTP, or some other service, right?
