User/Group/Share Reporting/Compliance Tool

Hello,

I was curious if there was a commerical tool available that allow for the tracking of what user/groups had access to files shares across the directory.

I have inherited a home built application that allows for that process - its a manual process but when kept up to date provides a nice report by user for network resources they have access to on the network.

This home grown app has 4 sections essentially.  The UI is web based with a SQL backend.
The first section provides an area to enter in the users, groups, and network resource
The second section provides an area to assign the users to groups or groups to users
The third sections provides an area to assign the users/groups to the network resource or the network resource to the users/groups
The fourth section is the reporting side where all the users are listed and by clicking on a user you can see the groups they belong to as well as the network resources they have access to.

The tool have been great for using in employee audits and we would like to continue using the tool but the current software sits on a 2003 box and its been confirmed from the original developer it won't survive a move to 2012.  The developer has suggested looking for a commercial app instead of rebuilding.

So my question is: Is there a commercial application with similar functionality for an SMB price?

thanks in advance
