List of access to Web Applications, Site Collection, Sites ?

Hello,

Is there a way to get an exhaustive list of access to Web Applications, Site Collection, Sites ?

I am tried to remove user retired, which left the company, which moved to another departement...

How to manage the access to SharePoint Web Applications, Sites, etc...

I have been able to get the WebApplication, Sites accesses using this execellent scriot from Brian http://geekswithblogs.net/bjackett/archive/2009/04/24/the-power-of-powershell-and-sharepoint-enumerating-sharepoint-permissions-and.aspx

Still looking to be sure all accesses are registered...

Thanks,

Dom
