Freeware to Generate AD Group Permission Setting

[ACWANG0048 () gmail com]

Dear all,

My company requests me to generate the AD groups's permission setting so that we can review the setup on a regular 
basis. So may I know whether there is any freeware that will gather the information from AD and generate the following 
(or similar) reports? 

Group Name        Folder Name     Permission
User A group      C:\main         Read+ write

Many Thanks,
Wang
