Bug Description

We are using Ubuntu in a university network with lots of ldap users. To automatically map ldap users/groups to local groups we are using pam_group.so. This has worked for years.

With the upgrade from Xenial to Bionic /etc/security/group.conf is not evaluated anymore by gnome-terminal as it runs as systemd --user. Xterm, ssh, su, and tty* however do work as expected. Only the default gnome-terminal behaves different.

According to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=851243 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756458 this might not be a bug, but a feature.

Nevertheless this behavior is very unexpected when upgrading from Xenial to Bionic and therefore should at least added to the changelog.

I am also using this feature and all previous versions of Ubuntu worked fine with this configuration. However with Bionic the GDM logins no longer add these local groups. Only no graphical logins like su, sudo, ssh, etc... add the appropriate local groups as per the /etc/security/group.conf.

This is a very important feature for us to be able to use Ubuntu with LDAP authentication in our computer labs for students and professors.
