  See RFC 2865 for the most recent definition of RADIUS.

  RFC 2865 limits the maximum length of an attribute.

  The limit is 253 bytes.  I suspect that many NASes and servers won't
handle that.  My guess is that 32 bytes is OK.  But for anything over 64
bytes, the odds of it working go down sharply.
