When running the ezfind CLI scripts updatesearchindexsolr, ezsolroptimize & ezsolrcommit as normal user, the scripts fails because of access rights in /var/lib/php/sessions (On Redhat/Fedora).

The doc does not indicate what user account that should be used and eZCLI warns about using root. Since the scripts does not need sessions (according to Paul B), this could easily be solved by setting the parameter use-session = false.
