Comment 2 for bug 1762391

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.
