Revision as of 19:25, 30 July 2011

This page chronicles the administrative changes to hope.progclub.org. If you make an administrative change you should document the change here. Changes are logged he in reverse chronological order with a time-stamp in the form YYYY-MM-DD hh:mm. You can use the time from whatever timezone you are in, or UTC if you're cool, but use 24 hour time. Don't worry if the changes you make have a time-stamp that is less than a time-stamp later in the page, put the latest changes at the top. Put a link to your wiki user account before the time-stamp so we know who's doing what. See the Administrative Reference for other information.

Adding user jj5

I had hoped to have LDAP and SSO operational before adding users to the any user machines, but it looks like there's nothing for it. Debuggin IPSec is a pain, and I need to login to hope all the time, and I'm sick of typing in the long random root password.
