Public bug reported: I'm using some ubuntu machine in a network where users data came from LDAP.
I've setup PAM/NSS to use LDAP account and all works as expected. Apart assigning local group to users, via pam_group. I've added to /etc/pam.d/common-auth (to the end): auth optional pam_group.so and added to /etc/security/group.conf: *; *; %sysops; Al0000-2400; adm,sudo,admin,dip,cdrom,floppy,plugdev,lpadmin,sambashare but groups are not added as expected, i'm not in 'admin' or 'sudo' group (eg, i cannot do administrative tasks) and if i fire up a terminal: gaio@dora:~$ id uid=1000(gaio) gid=1001(casa) gruppi=1001(casa),1000(sysops),1003(bbs) note that group assignment works, eg: gaio@dora:~$ ssh localhost gaio@localhost's password: Welcome to Ubuntu 18.04 LTS (GNU/Linux 4.15.0-23-generic x86_64) * Documentation: https://help.ubuntu.com * Management: https://landscape.canonical.com * Support: https://ubuntu.com/advantage * Canonical Livepatch is available for installation. - Reduce system reboots and improve kernel security.

This bug seems very similar to #880104 .
