Starting March 2023, external GitLab users of gitlab.science.ru.nl will be migrated to Science logins that only have access to GitLab. Until now, external GitLab logins were created in GitLab itself, separate from the Science login administration. By migrating the external GitLab users to Science logins with access to GitLab only, the management of these logins is improved. The requester (responsible for the Science login) can manage these logins in DIY....
