Introduction:
When we try to login to OBIEE 11g Analytics after installation, We were not able to login to portal and got the error saying “Authentication failed: invalid user/password”
The issue was caused because OBIEE Installed on Virtual Box and Loopback adapter was not installed , which is the pre-requirement for Installing OBIEE 11g in virtual box.
Solution:
To resolve this error , We Installed Loopback adapter in the windows server.
1. Open the Windows Control Panel.
Windows 2003: Select Start > Control Panel > Add Hardware.
Windows XP: Select Start > Control Panel, then double-click Add Hardware.
2. In the “Welcome” window, click Next.
3. In the “Is the hardware connected?” window, select Yes, I have already connected the hardware,
then click Next.
4. In the “The following hardware is already installed on your computer” window, in the list of
installed hardware, select Add a new hardware device, then click Next.
5. In the “The wizard can help you install other hardware” window, select Install the hardware
that I manually select from a list, then click Next.
6. In the “From the list of hardware types, select the type of hardware you are installing” window,
select Network adapters, then click Next.
7. In the “Select Network Adapter” window, make the following selections:

8. Click Next.
9. In the “The wizard is ready to install your hardware” window, click Next.
10. In the “Completing the Add Hardware Wizard” window, click Finish.
