I would use third party management tools as well from other vendors to manage active directory . Is this acceptable ?

Yes It is acceptable.

 

If you've ever been handed an Excel spreadsheet listing200 new employees starting next week, or if your user accounts are configured incorrectly because help desk staff clicked something they shouldn't have, or if you just want an easier way to manage Active Directory® besides opening Users and Computers every time, there are a number of free administration tools that can help. Some are built right into the Windows® OS, some come in a Resource Kit or the Windows Support Tools, and some are free third-party tools.  Follow this link
