If your login information is stored in Oracle you can integrate it with Sharepoint.
Essentially you have to create a website (Secured token service) that a user will be redirected to when they go to Sharepoint. This web site wil authenticate the user and then redirect the user back to Sharepoint and then user can login to Sharepoint.
Over the next several weeks I will go through the process of creating this integration. I recently completed this integration for a large client.
