Public bug reported: The patch 'debian/patches/01-cf.data.debian.dpatch' forces the default value of 'cache_effective_group' to 'proxy'. The original default value of this is 'none'. none is a special value which means it is unset. When none is present in this field, Squid does not explicitly set the gid of the squid process, and allows it's supplementary group memberships to be applied. When set to !none, squid forces the gid and ignores defined supplementary groups.
Since it is forced in Ubuntu to a specific value, there is no way to set it back to it's undefined state, and thus no way for squid to use supplementary group memberships, other than manually removing this patch. ** Affects: squid (Ubuntu) Importance: Untriaged Status: Unconfirmed -- debian/patches/01-* breaks useful use case https://launchpad.net/bugs/54965 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
