Password encoding/decoding

[Wichert Akkerman]

I am wondering if something goes wrong in the password handling. I know 
something goes wrong on my end in the UAM<->Chilli communication which 
mangles passwords: if I sent ABCDEFGHIJKLMNOPQRSTUVWXYZ as password
chilli decodes that to ABCDEFGHIJKLMNOPK<lots of binary>. But things go 
wrong on when that is sent to RADIUS as well. Here is the FreeRadius log 
output for the same request:

which shows that my bad password has become even more corrupted.

Wichert.
