Impact: Short-term unavailability (planned maintenance time: 15 minutes)

On 29.11. the Shibboleth Identity Provider of GWDG will be migrated to another software.
This can lead to short-term unavailability and it is possible that a new login is required.
The visual appearance also changes considerably and now resembles that of the Single SignOn (for example, known from ownCloud).
