Some patches for gnu-radius 1.1

Dear readers,

Let's first introduce myself, since this is my first posting to this
mailinglist. I am Maurice Makaay and I am working as an internet
applications developer for InterNLnet B.V. We are a medium-large 
Internet Service provider in the Netherlands, providing access, e-mail
and hosting services to our customers.

I just uploaded some patches to the gnu-radius Savannah site
(http://savannah.gnu.org/projects/radius). I would like to add a 
few comments to them here. These patches are:

2165 Extra Auth-Type "Crypt-Unix" for unix crypt() password check 
2166 Extra builtin rewrite function: tolower(string) 
2167 Do not log the Fall-Through attribute in detail.auth 
2168 conf "system-accounting yes|no" (to en-/disable utmp/wtmp) 
2169 Send authentication reject in case of a malformed user 
2170 Tunnel-Password attribute encryption (RFC2868 par. 3.5) 

I'll send separate messages for the comments on these patches to make 
replying easier and more structurized.

With kind regards,

Maurice Makaay
