Extending the Active Directory Schema
Historically, both Active Directory (AD) administrators and IT managers have been fearful of extending the AD schema. Much of this fear stems from Microsoft documentation in the Windows 2000 era that made schema extensions appear to be dangerous and something best done with extreme caution. However, with a bit of planning and due diligence, extending your AD schema doesn’t have to be something to fear.
