you can do this youself… all you need is VBScript with the MySQL ODBC connector…
Simply “fake” the task into the fog database if the vbscript conditions are met (ie. valid ad user).
I know for some other projects where I needed AD to controll the level of access someone had, I used a field that wasnt in use like title or zip code and used a numbering system 1 to 10 which denoted access levels.
Please feel free to credit me in your VBScripts once its all up and running… 😉
