Problem:

I am getting the Authentication Failed: User oiminternal denied Exception while starting the web logic start up.

Cause:

The OIMAuthenticationProvider db-password-encrypted padding is corrupted.

Solution:

Go to the $DOMAIN_HOME/config directory. Edit the config.xml and search the OIMAuthenticationProvider entry in the config file. Once you found the OIMAuthenticationProvider entry in the config file and modify the <ext:db-password-encrypted> value.

Restart the Web Logic Server and the issue will be resolved.
