RHCSA Practical Lab Series – Configuring User Accounts

🔍 Lab 9: Creating a User with a Specific UID

📌 Objective

In this lab, you will:

✔ Create a new user (developer99) with a specific user ID (4533)
✔ Set the password (cloudnetops123) for the new user
✔ Verify the user creation and authentication

📌 Step 1: Create the User with a Specific UID

🔹 Use the useradd command to create developer99 with UID 4533:

[root@node1 ~]# useradd -u 4533 developer99

📌 Explanation:

• useradd → Creates a new user account
• -u 4533 → Assigns the specific UID 4533 to developer99

🔹 Verify the user creation:

[root@node1 ~]# id developer99

🔹 Expected Output:

uid=4533(developer99) gid=4533(developer99) groups=4533(developer99)

✅ If UID 4533 is assigned, the user was created successfully.

📌 Step 2: Set the User Password

🔹 Set the password for developer99 to cloudnetops123:

[root@node1 ~]# echo cloudnetops123 | passwd --stdin developer99

📌 Explanation:

• echo cloudnetops123 → Sends the password as input
• passwd --stdin developer99 → Sets the password for developer99

🔹 Verify password change by switching to developer99:

[root@node1 ~]# su - developer99

📌 Expected Output (After entering the password cloudnetops123):

[developer99@node1 ~]$

✅ If the login is successful, the password has been set correctly.

📌 Step 3: Verify the User in /etc/passwd

🔹 Check the user entry in /etc/passwd:

[root@node1 ~]# grep developer99 /etc/passwd

🔹 Expected Output:

developer99:x:4533:4533::/home/developer99:/bin/bash

✅ If this entry exists, the user is properly configured.

✅ Final Summary

✔ Created a user developer99 with UID 4533
✔ Set the password to cloudnetops123
✔ Verified user authentication and system registration
