Here is a possibility, very slow, that uses only 'grep'.  But it 
will also print the Framed-IP-Address field when this is not the 
third but the second or first line after the Username:

grep -B1 -A3 "Username = dthn" yourfile | grep -A4 "Acct-Status =" | 
grep -e Acct-Status -e Username -e Framed-IP-Address -e --
