How to set CIFS share permissions.

Need help to setup share permissions in a CIFS share. we did the following...

from MMC permissions are set for the CIFS share named 'moldata'

1.In share permission - everyone - change ,read

2.In share security- Evryone -full control.

we have many subfolders under moldata.each subfolder is for different users/groups.Permissions are set for these folders as requested by the users.

Our problem is each user is able to rename other folder under 'moldata' but they can't see the contents or not even able to delete.Could any one help me

how we can stop even changing/modifying  the  other folders which they don't have access.

Any Help???

Thanks
