When you first install the Pentaho BI server, the login screen includes an option to Login as an Evaluator, either as an Administrator (Admin) or a Power User (Suzy). While this is handy if you just want to check the software out, its a huge security hole if you plan to move to production mode. The good news is that removing that functionality involves editing one configuration file to change a couple of settings.
Open a terminal and navigate to where the BI-Server was installed. On my system that is /opt/pentaho/biserver-ce. Drill down into the pentaho-solutions folder, and then to system folder.
Using a text editor, open the pentaho.xml file.
Look for the option login-show-user-list. It should look like this
--> <login-show-users-list>true</login-show-users-list> <!--
Change the value “true” to “false”.
Now look for the option node <login-show-sample-users-hint> which should follow the first one.
--> <login-show-sample-users-hint>true</login-show-sample-users-hint> <!--
Again the value should by default be “true”. Change it to “false”.
Save the file and exit. Restart the BI-Service daemon, and the option to Login as an Evaluator should no longer appear. Be sure to change the default Admin password, and remove the Suzy account to make your system more secure.
