Exception in Active Directory plugin when accessing web UI

[Sebastian Schuberth]

Hi,

since today I'm getting the following exception in Jenkins 2.5 with active-directory plugin 1.47 when accessing the web UI (even unauthenticated):

java.lang.IllegalArgumentException: Cannot pass null or empty values to constructor

I looks a bit like the issue at [1], but the stack trace is slightly different. Has anyone else seen this? As a work-around I've tried to downgrade the active-directory plugin to version 1.46 and also version 1.38, and upgraded Jenkins to version 2.8, both without any luck.
