Authentication methods (LDAP, SAML) in Jenkins - Mini Project: Build & Apply

Configure Jenkins Authentication with LDAP and SAML

📖 Scenario: You are setting up Jenkins for a company that wants to secure access using centralized authentication methods. The company uses LDAP for employee directory and SAML for single sign-on with their identity provider.

🎯 Goal: Learn how to configure Jenkins to authenticate users using LDAP and SAML methods step-by-step.

📋 What You'll Learn

Basic Jenkins installation

Access to Jenkins configuration files

LDAP server details (hostname, root DN, user search base)

SAML identity provider metadata URL

💡 Why This Matters

🌍 Real World

Companies use LDAP and SAML to centralize user login and improve security in Jenkins.

💼 Career

Understanding Jenkins authentication methods is essential for DevOps engineers managing secure CI/CD pipelines.

1

Create LDAP Configuration in Jenkins

Create a dictionary called ldap_config with these exact entries: server: "ldap.company.com", root_dn: "dc=company,dc=com", and user_search_base: "ou=employees,dc=company,dc=com".

Jenkins

Need a hint?

Use a Python dictionary with keys server, root_dn, and user_search_base.

2

Add SAML Configuration Variable

Create a variable called saml_metadata_url and set it to the string "https://idp.company.com/metadata.xml".

Jenkins

ldap_config = {
    "server": "ldap.company.com",
    "root_dn": "dc=company,dc=com",
    "user_search_base": "ou=employees,dc=company,dc=com"
}

# Your code here

Need a hint?

Assign the exact URL string to the variable saml_metadata_url.

3

Combine LDAP and SAML into Jenkins Auth Config

Create a dictionary called jenkins_auth_config with two keys: ldap set to the ldap_config dictionary, and saml set to the saml_metadata_url string.

Jenkins

ldap_config = {
    "server": "ldap.company.com",
    "root_dn": "dc=company,dc=com",
    "user_search_base": "ou=employees,dc=company,dc=com"
}

saml_metadata_url = "https://idp.company.com/metadata.xml"

# Your code here

Need a hint?

Use a dictionary with keys ldap and saml referencing the existing variables.

4

Print Jenkins Authentication Configuration

Write a print statement to display the jenkins_auth_config dictionary.

Jenkins

ldap_config = {
    "server": "ldap.company.com",
    "root_dn": "dc=company,dc=com",
    "user_search_base": "ou=employees,dc=company,dc=com"
}

saml_metadata_url = "https://idp.company.com/metadata.xml"

jenkins_auth_config = {
    "ldap": ldap_config,
    "saml": saml_metadata_url
}

# Your code here

Need a hint?

Use print(jenkins_auth_config) to show the combined configuration.
