#32 Getting java error messages after entering worng crdentials

[dahf]

Hi,
I’ve successfully installed IntegraTUM WebDisk last release (0.44) on a RHEL 6.5 server with Apache Tomcat 6.0.39.
All seem to work as long as users provide correct credentials. But once they enter wrong either username or password they are getting inconsistent java errors which users don’t want to see them
I need help to change those errors to meaningful messages to users.

Here are some of those messages:
