minimum additional software for OID
Ok, I've been spinning my wheels on this for several days now. I need to investigate using 'global' users to authenticate with Active Directory. It is my understanding that to do that I need to install OID. It is my further understanding that Oracle's packaging of OID has changed with versions, and maybe even mid-version. It would appear that I need Fusion Middleware, but at https://shop.oracle.com/pls/ostore/f?p=dstore:2:0::NO:RIR,RP,2:PROD_HIER_ID:4509883114661805720002 it appears that even "Fusion Middleware" is just an umbrella marketing name for various packaged products.
So I need to get pointed in the right direction on this. What is the minimal software I need to implement AD authentication?
