Message in Computers & Services main page

Hi, When I start Server Admin and go to Computers & Services and click on my OD master I see the following message on it's main screen... "This server contains new or upgraded services that need to be configured to use single sign-on Kerberos authentication. Services that already use Kerberos on this server will not be affected. Select Open Directory in the Computers & Services list, then click Settings." In Settings I see nothing different or anything that looks like it needs attention. Anyone have any idea what the services could be? Thanks. Pat.
