Sorry, but i think you are asking the "wrong question":

"auditing" is a feature in AIX, which you may or may not to switch on. I suppose you probably won't need it.

What do you want to achieve? Please tell us some of the requirements and we eventually could tell you what is needed to fulfill them.

"sudo" can be brought to log any usage of "su", but of course anybody with the possibility of becoming root will be able to circumvent the logging-mechanism given sufficient intent and sufficient effort.

What you could do is (this is just a sketch!):

1) set up a logging server. Login on this server is prohibited save for the person checking the logs.

2) disable root login and "su - root" on the servers you want to audit.

3) allow "su - root" through sudo. Put the mechanism into a small script, which not only issues the "sudo su ...." command but also sends a log entry to the logging server mentioned in 1). This prevents the log files from being altered by the people becoming root on the machine under audit. (If you'd save it somewhere on the same machine root would be able to edit them.)

NAME
bsmconv, bsmunconv - enable or disable the Basic Security Module (BSM) on Solaris SYNOPSIS
/etc/security/bsmconv [rootdir...] /etc/security/bsmunconv [rootdir...] DESCRIPTION
The bsmconv and bsmunconv scripts are used to enable or disable the BSM features on a Solaris system. The optional argument rootdir is a list of one or more root directories of diskless clients that have already been configured. See smdiskless(1M). To enable or disable BSM on a diskless client, a server, or a stand-alone system, logon as super-user to the system being converted and use the bsmconv or bsmunconv commands without any options. To enable or disable BSM on a diskless client from that client's server, logon to the server as super-user and use bsmconv, specifying the root directory of each diskless client you wish to affect. For example, the command: myhost# bsmconv /export/root/client1 /export/root/client2 enables BSM on the two machines named client1 and client2. While the command: myhost# bsmconv enables BSM only on the machine called myhost. It is no longer necessary to enable BSM on both the server and its diskless clients. After running bsmconv the system can be configured by editing the files in /etc/security. Each diskless client has its own copy of configu- ration files in its root directory. You might want to edit these files before rebooting each client. Following the completion of either script, the affected system(s) should be rebooted to allow the auditing subsystem to come up properly initialized. FILES
The following files are created by bsmconv: /etc/security/device_maps Administrative file defining the mapping of device special files to allocatable device names. /etc/security/device_allocate Administrative file defining parameters for device allocation. ATTRIBUTES
