Alter error message
You may want to do some customization, like alter the error message prompted on the screen.
In this case, you can find the most text originated in the file called "messages.properties" in the folder
C:\Program Files\Deepnet DualShield\tomcat\dualapp\das5\WEB-INF\grails-app\i18n
If you can't find the string in that file, please also check it in "app.properties" which is in another folder
C:\Program Files\Deepnet DualShield\tomcat\ssoapp\appsso\WEB-INF
