he question is – if you can mix LDAP and other type of authentication. In one word – yes and no.
Here’s what Oracle suggests:
1. You can have internal authentication and LDAP authentication. eg users in the rpd, and users in the LDAP.
For users not defined in the repository, the presence of a defined session system variable USER determines that external authentication is performed.
So using this method, you can have groups with internal users using the internal security, and groups with users that use the LDAP authentication.
But you cannot mix external table and LDAP authentication for example, as you cannot have different connection pools on same init block.
2. The best option would be to create your own authentication Dll (Custom authentication) so you will have full control on what systems you will lookup for the user account.
You can write your own DLL in C++ , and have OBI Server invoke it. BI just pass the username/pwd received, and wait for an authenticated/no authenticated message from the dll.
This exists since 10.1.3.2.
We provide an example of such dll.

I wonder if anyone tried it – I think that at this time, it’d be easier to work around the requirement by using standard methods. Let’s see what John Minkjan might say about it.
