Illegal chars in a username (Was [Help-gnu-radius] listening but deaf?)

Sure, there is. You can change the set of characters allowed in an
username. To do so, you'll need to add desired characters to
valid_chars[] array in radiusd/auth.c:109. (Note, that all
alphanumeric characters are always allowed.) In your case, the
following patch will do the work:

--- radiusd/auth.c      Tue Apr 17 09:43:34 2001
