How to reproduce:

1. ASSERT: make sure you have an openshift user account that is not listed in the OpenShift Explorer
2. EXEC: open up the OpenShift Explorer
3. EXEC: in central, hit OpenShift Application
4. EXEC: in the upcoming authentication dialog, provide your user (that is not listed in the explorer) and hit Next

Result:

1. ASSERT: the user is not listed in the OpenShift explorer even though it was used and valid.

I think we should add this new user to the OpenShift explorer since it was used and proven to be valid.
