open source user audit software ??

[Michael Gale <michael.gale () bluesuperman com>]

Hello,

I believe that IBM has a product called Tivoli which has a component 
that can do the following:

- A new employee is starting, the PM clicks the required access through 
a web portal. Which then notifies each person required to make the 
changes or accounts, plus could make the accounts if allowed.

It will provide an audit trail of who requested the access and who 
approved the request.

It can also provide an alert when new accounts have been created with 
out using the software.

Does anyone know of any open source tools that can do this ??
