detail module - detailfile problem

[tzieleniewski <tzieleniewski@o2.pl>]

Hi!

I am trying to set the destination file for detail log file in the detail file module in the following way
detailfile = ${radacctdir}/%{check:Huntgroup-Name}/detail-%Y%m
but radius instead allways writes to the following destination??
rlm_detail: %A/%{Client-IP-Address}/detail expands to /var/log/radiusd/radacct/127.0.0.1/detail

I have one more small question:
How can I take from the User-Name attribute value wich is of the form username@domain.com the domain part in order to forward logging to the 
{radacctdir}/"cutted_domain_part"/detail-%Y%m file

I kindly ask for your help.
Best Tomasz
