5 Select Identity Provider
For user authentication, you can choose WebLogic security in conjunction with your choice of external authentication identity provider, or, if you already use EPM Shared Services, you can continue to use it.
If you use EPM Shared Services, you must install and integrate Essbase On-Premise with a separate EPM instance where you have installed only Foundation Services. Please note that an existing EPM installation can't be reused. You can migrate users and application permissions between the two Foundation Services.
