I don't know why "logged in users can do anything" means Jenkins will happily allow non-authenticated users to view project details and access artifacts... Regardless, I need to know how to get Jenkins to allow logged in users to to anything AND hide EVERYTHING for users who AREN'T logged in. Help please?
This can be done with the Role-Strategy plugin.
Install the plugin, add a new group called "Anonymous" and uncheck everything. Then you want to add another group called "authenticated" and check everything. Add your existing users to this group. Jenkins will immediately prompt you for a login this way.
You can use https://wiki.jenkins-ci.org/display/JENKINS/Role+Strategy+Plugin
it allows to specify to define roles and assign roles to users, users with no roles won't even see the jenkins ui.
Answer to an old question but I came searching here as I am trying to auto spin up a Jenkins instance on Docker and found the same issue.
Good chance this option wasn't available when the question was asked. As of this moment (v2.222.3 but not sure how far back), it turns out you can do this without installing any additional plugins.
Manually
Navigate to Global Security (Jenkins > Manage Jenkins > Global Security)
Update the Authorization section to "Logged-in users can do anything".
UNCHECK Allow anonymous read access
Any unauthenticated access will redirect to login now.
I would note that if you setup Jenkins through the setup wizard then anonymous read access is disabled by default. If you want this behaviour AND want to configure jenkins automatically, read on.
Automated with Docker
My situation is that I wanted to check out my repo, run my compose file and have all my config/users/plugins etc ready to go. Great post here with more detail if interested.
In a nutshell:
Dockerfile
FROM jenkins/jenkins:lts-alpine
# Disable setup wizard since security.groovy creates our user
ENV JAVA_OPTS="-Djenkins.install.runSetupWizard=false"
COPY security.groovy /usr/share/jenkins/ref/init.groovy.d/security.groovy
security.groovy
#!groovy
import jenkins.model.*
import hudson.security.*
def instance = Jenkins.getInstance()
// Create Admin User
def hudsonRealm = new HudsonPrivateSecurityRealm(false)
hudsonRealm.createAccount("admin", "admin") // Dont do this. This is bad
instance.setSecurityRealm(hudsonRealm)
// Set Auth to Full Control Once Logged In and prevent read-only access
def strategy = new FullControlOnceLoggedInAuthorizationStrategy()
strategy.setAllowAnonymousRead(false)
instance.setAuthorizationStrategy(strategy)
instance.save()
In particular, strategy.setAllowAnonymousRead(false) is what's needed
Additionally, if you use GitHub as your version control system -- you can use the GitHub OAuth plugin. Once the "Anonymous" reach your page, they will be redirected to GitHub automatically.

Facing issue related to adding new users in Jenkins as I am not able to see Manager user options. Jenkins is using ldap for authentication. I believe I don't have admin access to add new user and our old admin has left the team. Is there any way get all admin access from server itself ?
This is a common problem when making changes to secure Jenkins. Whenever you make a mistake and get locked out you may end up having to disable the security in the config.xml. Look for the following line and set it to false. Ofcourse, make sure to make a backup before changing this as the whole security configuration will be erased after you restart Jenkins
<useSecurity>true</useSecurity>
I have a Jenkins server with multiple users that are able to create and modify Global credentials. Is there any way I can audit and see who did what with the credentials - who modified them, who added new creds, etc. Preferably, presented in nice way similar to Job Config History plugin. Thanks
I had a similar question a few days ago. You can use the Audit Trail Plugin (GitHub) to audit changes to credentials. It logs the HTTP requests that modify credentials. However, it doesn't have a "config history"-style visualisation.
(Soon, it may also be able to log what jobs access the credentials)
You can do that using the Job Configuration History Plugin.
Link should be something like:
https://your.jenkins.url/jobConfigHistory/history?name=credentials
What I noticed is that all changes are shown as if they were been done by 'System' - though they all were done by a specific user.
I'm hosting a project on my Jenkins server. That project has a GitHub repo and I have it set up so it automatically builds new commits. In order for that to work, I need to input credentials for a github account that has full access to the repo.
The problem is, that if I want him to add his login info to the credentials list, I'd have to give him acces to all credentials on the server (I don't want that).
I tried using the credentials under "{username}" > "Credentials", but those didn't show up in the project setup (even with 100% access to everything on the server).
Is there a way for the user to store his credentials and use them for the project without giving him full access to all credentials on the server?
Add the user's credentials under Global security and then allow project based Matrix Authorization Strategy per project as shown:
I found the answer in this mailing list entry:
In short: You need to
install and activate the Authorize Projects Plugin,
enable "run as specific user" strategy in global security settings,
enable this for the project in question.
This allows you to use the credentials for this specific user.
Enabling ssh-agent is the final step to make this work conveniently.
On my Jenkins build server, I want to set an Authentication Token so that only users that know the token can fire off builds. (As described here.)
This doc page says that it should be configurable under my job's "Build Triggers" configuration.
However, my server has no such fields, and I'm running the latest version (1.546). Mine looks like this:
.
As you can see, this doesn't really look like the docs say it should.
How can I set this token?
You're missing the Trigger builds remotely (e.g., from scripts) Build Trigger:
This is only visible with Security enabled. To get this option from a freshly downloaded 1.546 WAR, I changed Configure Global Security from Anyone can do anything to at least Logged-in users can do anything. For ease/speed of testing, under Security Realm I selected Jenkins’ own user database and Allow users to sign up:
You can go to http://Jenkins-IP/jobs/me/configure to check and change your API access token. Also check whether the user you intend to use has necessary permissions to execute the builds in Manage Jenkins>Configure Global Security
Each jenkins user gets an authentication token - applicable since version 1.426 (more).
You can see yours, provided you are logged in your jenkins server, at http://your.jenkins.server/me/configure
(press 'show API token' button)
Then you can copy and paste it in your scripts (e.g. see here for an example usage).
When I go to mydomain.example:8080 there is no authorization mechanism by default. I have had look at the configuration area but cannot find anywhere to add a basic username and password
Go to Manage Jenkins > Configure Global Security and select the Enable Security checkbox.
For the basic username/password authentication, I would recommend selecting Jenkins Own User Database for the security realm and then selecting Logged in Users can do anything or a matrix based strategy (in case when you have multiple users with different permissions) for the Authorization.
Assuming you have Manage Jenkins > Configure Global Security > Enable Security and Jenkins Own User Database checked you would go to:
Manage Jenkins > Manage Users > Create User
Try deleting the .jenkins folder from your system which is located ate the below path.
C:\Users\"Your PC Name"\.jenkins
Now download a fresh and a stable version of .war file from official website of jenkins. For eg. 2.1 and follow the steps to install.
You will be able to do via this method
You need to Enable security and set the security realm on the Configure Global Security page (see: Standard Security Setup) and choose the appropriate Authorization method (Security Realm).
Depending on your selection, create the user using appropriate method. Recommended method is to select Jenkins’ own user database and tick Allow users to sign up, hit Save button, then you should be able to create user from the Jenkins interface. Otherwise if you've chosen external database, you need to create the user there (e.g. if it's Unix database, use credentials of existing Linux/Unix users or create a standard user using shell interface).

If installed as an admin, use:
uname - admin
pw - the passkey that was generated during installation
