Question on security..

[Richard Bates]

I know login failures are logged in /var/log/auth.log

is there a way to log the login of users in this log
say something like

Jan 15 10:59:00 MyServer sshd[91869]: User bates authenticated from  
172.18.1.139
Jan 15 10:59:00 MyServer sshd[91869]: User bates Disconnected from  
172.18.1.139
