Description OSIDB Bzimport 2025-04-15 09:56:14 UTC

On sites with Multi-Factor Authentication enabled, it was  possible to use course self enrollment after passing only the first login factor (such as passing a username/password check). The user should also have to pass a second login factor before gaining access to self enrollment.
