[tac_plus] Question about logging with tac_plus

[Cosmin Neagu]

Hi,
I want to know if it is posible to make tac_plus log into the default 
log file ( tac_plus.log ) logs when users ask for access on network 
equipment:
Something like:
Tue Apr 10 09:41:36 2012 : Auth: Login OK: [cosmin/parola] (from client 
172.31.1.211 port 1)

where 172.31.1.211 is the network equipment who asket tacacs for access 
on behalf of the user.

I searched on internet but except:
accounting file = /var/log/tac_plus.acct
I did not find anything regarding logging user attempts to connect.
Thanks.
