As a result of the migration that happened over the weekend, a number of services are failing to authenticate. We're currently trying to rectify this, and we expect that most services will be properly operational within an hour.

The underlying reason for this is that the migration introduced a requirement for secure connections to the central LDAP authentication servers, and not all applications are configured to support this. As an interim measure, we're going to revert the change and re-allow unsecured connections. We'll then attempt to identify and correct any services that are not configured to support the secure version.
