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?
