We're running EPM 11.2.1.4 and OBIEE 12.2.1.3 on Windows servers. WebLogic is configured with an Active Directory authenticator looking at Global Catalog port 3268 from the root of a multi-domain forest. The AD guys are looking to upgrade the Domain Functional Level from 2008 R2 to 2016. Has anyone gone through this yet and, if so, was there any fallout in terms of WebLogic authentication or Oracle application functionality? Is there anything I should do to prepare?
