User management improvements

November 23, 2017

Management of local users and groups (i.e. those in /etc/passwd and /etc/group) is done using the LCFG auth component.

This has led to the development of a new high-level LCFG::Client::Resources Perl library which can be used to import, merge and export resources in all the various required forms. The intention is that eventually all […]
