Differences Between Development System and
Productive System
The configuration for productive mode provides for more security than development mode. The following setting are affected:
· Password policy
In development mode, the default password policy is set so that passwords do not expire. In productive mode, the default value is 90 days.
● Error handling from the HTTP Provider service
In development mode the property DetailedErrorResponse is set to true, meaning that the exception stack trace is displayed when errors occur. In productive mode, this property is set to false, meaning that such detailed error messages are not displayed.

Therefore, if you switch an installation from development to productive mode, we recommend you adjust these settings accordingly.
