[sudo-users] Log configuration

[javaluno]

Hello,

Is it possible to configure the sudo log to register the logname instead of
the username?
 I mean, if  user A logs and su (switch user) to user B and then uses SUDO
to execute commands, the log  will register actions of user B. What I need
is to register these actions as being executed by user A.

Is it possible?

Thanks in advance,

J.
