BEA-090402:OBIEE Boot Identity Not Valid - Authentication Denied [SOLVED]

Issue: We faced the issue on a Linux Server when trying to Start Weblogic Script. 

<Authentication denied: Boot identity not valid; The user name and/or password from the boot identity file (boot.properties) is not valid. The boot identity may have been changed since the boot identity file was created. Please edit and update the boot identity file with the proper values of username and password. The first time the updated boot identity file is used to start the server, these new values are encrypted.>

Cause: This issue could be because the credentials inside the boot.properties file is not valid. This credentials could change while stopping the weblogic server and you are prompted to give password here and if you give the wrong credentials during shutdown it will be written to the boot.properties file.

Issue in Terminal Window

Resolution: The issue can be resolved by changing the password in the boot.properties file and restarting again.
