OBIEE 11g logon process: overview
Posted by sranka on October 16, 2011
When a user logs in via the analytics web app UI, the request containing the user credentials will be sent to the BI Presentation Server which in turn passes the request on to the BI Server. The BI Server is authoritative for user authentication. In the first instance the BI Server will attempt to authenticate the user credentials via a web service call to the BI Security Web Service, which is deployed in the WebLogic Managed Server and is protected by a WS-Security policy which requires the BI Server to itself authenticate itself to Oracle Web Services Manager before the call can be received by the BI Security Service. The BI Server uses credentials stored in the Credential Store (CSF) under the oracle.bi.system map and uses those to authenticate itself to the BI Security Service when attempting to authenticate the credentials specified by the user. If there is a problem with the BI System User credentials, or the Oracle Web Services Manager, then the call from the BI Server to the BI Security Service will fail and hence so will the overall logon process.
Hope This helps.
