https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=41458 --- Comment #6 from Slava Shishkin <slavashishkin@gmail.com> --- Thanks for checking this. Yes, I understand your point. On your test system the UID and GID are the same, so the problem does not manifest there. However, on systems where the GID differs from the UID, SIP starts with a group privilege error. This happens because Koha currently passes the effective UID as the Net::Server "group" parameter. Problematic code: push @params, 'user=' . $>; push @params, 'group=' . $>; Here the UID ($>) is passed for both user and group, while Net::Server expects a GID for the "group" parameter. This works on your system only because UID == GID. In that case the incorrect value happens to work by accident. -- You are receiving this mail because: You are watching all bug changes.
