I usually use the java DNS/DHCP utility anyway, but I noticed that any instance of iManager we have that is current does not show the OES DHCP role in the left pane, even though the plugin exists and is configured for use in the collection. Not even as the admin object, which owns everything in the one single collection we have.
It does, however, show on an older instance of iManager we have running 2.7.3.
Was this somehow disabled in 2.7.4? I can't find that anything is misconfigured. I've enabled other roles before and assigned the member rights correctly, we're even created some custom ones.
