Diffrence between Active Directoy and Active Directory Services
I'm totally new in networking topics, so excuse my ignorance.
A friend of mine told me that there are two types of Microsoft active directories: one is named "local active directory" and the other is named "active directory services". The active directory services is created along with the local active directory.
He wants a web application in his company capable to authenticate users through both active directories. If user is local, then the web application should authenticate that user against the local active directory. If the web application detects that user is external, then it should authenticate it against the active directory services.
