/etc/group is not in Sync with Group Assignment in GUI

[rac-hh]

Until 24.1.10 the unix groups were properly populated. Now it seems they are pupolated rarely with e.g. logged in users.
But some programms like /usr/local/libexec/squid/ext_unix_group_acl rely on full managed groups.

Is it possible to get the file full in sync with the GUI again?
