Beginning with 2nd June, only the "Single Sign On" option for login to the GitLab web interface will be possible. If you don't have an MPCDF wide second factor so far, please get one at our SelfService (https://selfservice.mpcdf.mpg.de). The GitLab internal second factor will not work.
I tried the new system, e.g. recreated my dev setup with the current develop. A few small things came up in the process. See review threads.
