[ale] Auditing root shells

[jb at sourceillustrated.com (John Wells)]

Guys,

We have a need to capture everything an admin does while logged in as root
and another power login (postgres).  This is driven by a number of forces,
not the least of which is Sarbanes Oxley.

Are there any tried and true (and secure) auditing solutions that offer
this capability?

Thanks, as always.

John
