# User Management Solutions

This section contains my solutions to various user management scenarios from the practice exercises.

## Scenario: Creating Users with Specific Requirements

### Original Problem
From Practice Scenarios v3: Create a user named 'john' with a custom shell and home directory.

### Environment
- OS Version: Rocky Linux 8.x
- Initial State: No user 'john' exists
- Required Outcome: User 'john' created with specific requirements

### Solution Steps
1. Create the user with specific requirements
   ```bash
   # Create user with custom home directory
   sudo useradd -m -d /custom/home/john -s /bin/bash john
   
   # Set password
   sudo passwd john
   ```
   This creates the user 'john' with a custom home directory and bash shell

2. Verify user creation
   ```bash
   # Check user entry in /etc/passwd
   grep john /etc/passwd
   
   # Verify home directory
   ls -la /custom/home/john
   ```

### Key Learnings
- Understanding of useradd command options
- Importance of verifying user creation
- Best practices for user management

## Skills Demonstrated
- User Account Management
- Command Line Proficiency
- Security Best Practices
- System Verification

# Scenario: Creating Users with Specific Requirements

## Original Problem
- Create a new user called 'analyst1' with home directory '/home/analyst1'
- Create a group called 'datateam'
- Add 'analyst1' to 'datateam'
- Create a directory '/data/reports' owned by 'datateam' with SGID set
- Ensure members of 'datateam' can read/write, others can only read
- Set password expiry for 'analyst1' to 90 days

## Environment
- OS Version: RHEL 9.5
- Initial State: No user 'analyst1' exists
- Required Outcome: User 'analyst1' created with specific requirements

## Solution Steps
1. Step 1 - Create the user 'analyst1'
   ```bash
   sudo useradd -m -d /home/analyst1 analyst1
   ```
   This creates the user 'analyst1' with a home directory '/home/analyst1'

2. Step 2
   ```bash
   sudo groupadd datateam
   ```
   This creates the group 'datateam'

3. Step 3 - Add 'analyst1' to 'datateam'
   ```bash
   sudo usermod -aG datateam analyst1
   ```
   This adds 'analyst1' to the 'datateam' group

4. Step 4 - Create the directory '/data/reports' owned by 'datateam' with SGID set
   ```bash
   sudo mkdir -p /data/reports
   sudo chown :datateam /data/reports
   sudo chmod 2775 /data/reports
   ```
   This creates the directory '/data/reports' owned by 'datateam' with SGID set

5. Step 5 - Ensure members of 'datateam' can read/write, others can only read 
   ```bash
   sudo chmod 2775 /data/reports
   ```
   This ensures members of 'datateam' can read/write, others can only read

6. Step 6 - Set password expiry for 'analyst1' to 90 days
   ```bash
   sudo chage -E $(date -d '90 days' +%Y-%m-%d) analyst1
   ```
   This sets the password expiry for 'analyst1' to 90 days

## Verification
Commands used to verify the solution works correctly

## Key Learnings
- Understanding of useradd, groupadd, usermod, mkdir, chown, chmod, chage commands
- Importance of verifying user creation
- Importance of setting password expiry

## Additional Notes
> [!NOTE]
> This scenario is a good example of how to create a user with a specific home directory, add them to a group, create a directory owned by the group with SGID set, and set password expiry.
