This bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=800151
is fixed in jessie (in 2.2.5+dfsg-0.2), but current backport in wheezy is from an older version (2.2.5+dfsg-0.1). Please backport again freeradius from jessie to wheezy to fix it. If possible mark the bug as closed by the new backport.
Thanks.
