Scenario: As an administrator, you have forgotten the password of the Jenkins First Admin User Account , and need to reset the same.

Test Data: For uniformity and simplicity, I have used the same Test Data for both the Ubuntu and Windows VM's during testing.

1. First Admin User Details:
2. Username: jenkins21900
3. Password: password
4. Full Name: jenkins21900
5. Email Address: kharad.afour@gmail.com
6. Jenkins URL: http://localhost:8080

Test Instructions: Perform all steps with Administrator/Root user.

Pre-requisites
1. Install Jenkins with all the pre-requisites in place.
2. Create a Jenkins First Admin User Account valid user-name and password in the Jenkins installation.
3. Validate that you can successfully login as the Jenkins First Admin User Account.

Steps to Replicate: - Linux/Ubuntu
1. Navigate to /var/lib/jenkins/ and edit the config.xml file in an editor of your choice.
2. Search for the <useSecurity>true</useSecurity> and change it to <useSecurity>false</useSecurity>
3. Restart Jenkins, by executing the sudo service jenkins restart command.
4. Access the Jenkins URL, and observe that you are not prompted for the password and that the Dashboard loads directly.
5. Navigate to /var/lib/jenkins/ and load the config.xml file in an editor of your choice.
6. Search for the <useSecurity>false</useSecurity> and observe that it has changed to <useSecurity>true</useSecurity>

Steps to Replicate: - Windows
1. Stop the Jenkins service.
2. Navigate to C:\jenkins\config.xml and edit the config.xml file in an editor of your choice.
3. Search for the <useSecurity>true</useSecurity> and change it to <useSecurity>false</useSecurity>
4. Start the Jenkins service.
5. Access the Jenkins URL, and observe that you are not prompted for the password.
6. Click on sign Out to Sign Out from Jenkins.
7. Navigate to C:\jenkins\config.xml and load the config.xml file in an editor of your choice.
8. Search for the <useSecurity>false</useSecurity> and observe that it has changed to <useSecurity>true</useSecurity>

Expected Result: The <useSecurity>false</useSecurity> should not change to <useSecurity>true</useSecurity>

Actual Result: The <useSecurity>false</useSecurity> has changed to <useSecurity>true</useSecurity>
