Hiding detailed login messages
By default, Planon Software Suite provides extra information when a login fails. For example:
Account expired
Account locked
Server in upgrade mode
To hide the detailed login messages, add the following parameters to the Java Additional Parameters of the application server service wrapper configuration file located in ...\Server\tanuki\appserver\conf:
-DplanonDiscloseHTTPError=false
-DplanonDiscloseLoginFailureReason=false
* 
If you do not have the above parameters, this is handled as if the parameters are set to True.
