> I went to enable kerberos and after Configure Identities and Stop Services,
> the wizard performs a PUT and moves to the Kerberize Cluster step (create
> principals, create keytabs, etc)
> The UI hung since the PUT was taking a while (30+ seconds). On the wizard,
> you had the wizard shell, the title and a disabled next button. After some
> time, there was an error (backend) and an error dialog popped up.
> Minimum change is to have a spinner in the wizard area after the PUT to at
> least give the user a sense something is happening. Otherwise, looked like I
> was broken right away, vs. a PUT taking a really long time.
