SLES user Management
SLES 15 support both: local user and domain user management
In this article : we will discuss managing local users
As we know in windows operating system: local users are created in file C:\WINDOWS\
In SLES 15 :
users are created in in /etc/passwd
and their password are encrypted in file /etc/shadow
Also group are created in file /etc/group
Regarding users profile
Users profile is stored at /home , except root account who has /root as exceptional
Managing Local users graphically with Yast
Yast [Yet another Setup Tool ] is great tools for SLES administration

let’s go
Add local user command
useradd [username]Add local user parameters
- -m create home for user as default
- -c > add comments
- -u > specify UID
- -g > add user to group
- – e > set account expire date
- – p > set encrypted password for user
