  Because they are needed only for MS-CHAP authentication.  They are
*not* needed anywhere else.

  Perhaps Alvarion could explain why they need these attributes. They
are *not* needed in the WiMAX spec, so far as I recall.  FreeRADIUS
works with a number of WiMAX systems (Nokia, Motorola, etc.)

  What's so different about Alvarion?

  There has been little mention of it here.
