             Summary: Credentials dialog: Inform user about a non-valid OpenShift server url in a user-friendly way
                 Key: JBIDE-15055
                 URL: https://issues.jboss.org/browse/JBIDE-15055
             Project: Tools (JBoss Tools)
          Issue Type: Enhancement
          Components: openshift
            Reporter: Andre Dietisheim
            Assignee: Andre Dietisheim
            Priority: Minor
             Fix For: 4.2.x
         Attachments: could-not-connect.png, could-not-verify-credentials.png

A user has currently an option to provide his own openshift URL. However, if this URL is not correct, the wizard complains about wrong credentials. It would be helpful if the wizard can check if the URL is correct and if not, show a meaningful message to the user. 

# ASSERT: make sure you have an invalid URL in the libra_server key (either in the system properties, or in /etc/openshift/express.conf or in ~/.openshift/express.conf)
# EXEC: launch the OpenShift Application wizard
# EXEC: on the first page, provide username and password
# EXEC: hit "Validate" or "Next"

Result:
The wizard informs you that your credentials are invalid

Expected:
You should get informed that the url of the OpenShift server is not valid
