Robert Joseph Evans commented on STORM-2214:
--------------------------------------------
Actually there was a change in 2.x a function in AuthUtils was renamed
{{s/PullConfig/pullConfig/}} So if you want the change I can backport it, but
it will be a 1 character difference.

> The UI and supervisors authenticate to nimbus through kerberos. But they
> initiate a new connection each time they do so, and even use a new Subject
> for each connection. This means that the client must fetch a new service
> ticket each time and adds a lot of load on the KDC.
> In order to reuse the subject between sessions we propose cacheing the Login
> instead of creating a new one each time.
