Hi,
I removed a user from an LDAP group about a week ago. Today, this user still shows as member of the group with the Linux command groups. Also, the group (Administrators) appears twice in the output of the command id:
uid=10000(username) gid=10000(Administrators) groups=10001(users),10005(devel),10011(video),10015(ansible),10000(Administrators)
The command getent though shows the proper group assignation:
getent group | grep username | cut -d: -f1
users
devel
video
ansible
All of those groups are LDAP group.
