New user is not taking system default Group ID. System default group id for new user is 100. Whenever i create a new user, GID as well as UID increments by 1. I can understand UID but GID should be 100 for every new user. What is the possible reason? I am using Amazon linux AMI on EC2.
# adduser -D GROUP=100 HOME=/home INACTIVE=-1 EXPIRE= SHELL=/bin/bash SKEL=/etc/skel CREATE_MAIL_SPOOL=yes # useradd -m testuser # useradd -m testuser2 # cat /etc/passwd testuser:x:501:503::/home/testuser:/bin/bash testuser2:x:502:504::/home/testuser2:/bin/bash
