'useradd' without option '-a' means the new assigned group is replacing the previous group assignment. '-a' means 'append' to enable a secondary group assignment. I think '-a' is necessary to fit the requirement. # groupadd admin # useradd -aG admin mary # useradd -aG admin alice # useradd -s /sbin/nologin bobby

there is no -a switch in useradd... and you are creating the users from scratch... just make id "username" to check
