You can find the current freeradius dictionaries at https://github.com/alandekok/freeradius-server/tree/v2.1.x/share You can see that dictionary.microsoft and dictionary.merit are there and neither have spaces in the front of the lines. Both are included from the top-level dictionary (share/dictionary). According to 'git log', share/dictionary.microsoft has been present since Feb 2000. It includes attributes 11 (MS-CHAP-Challenge) and 25 (MS-CHAP2-Response). share/dictionary.merit has been present since May 2004, although it doesn't have as many attributes as in the page you linked. Are there specific ones you are missing?
