I installed jenkins on a CentOS system. Now I am able to open the jenkins web page on localhost:8080. I want to add a login required for accessing this url. I enabled security on 'Configure Global Security' page then set 'Unix user/group database' under 'Security Realm'. In Authorization part, I set 'Logged-in users can do anything'. By doing this configuration, only logged in user can do build and modification on jobs. But there is a problem that users can still read all the jobs information without log in. How can I prevent anonymous users to access my jenkins web page?
Using the "Matrix based security" helps you here. And then uncheck all the checkboxes from the Anonymous user.
Under the "Jenkins’ own user database" also uncheck the "Allow users to sign up" sign up option. This way you can prevent unwanted users.
Good luck!

I have recently switched to using AD login on my Jenkins instance but I notice Jenkins has restricted the functionalities I can access including the Manage Jenkins view:
I can no longer login with the admin user after this re-configuration since it returns incorrect password from the Active Directory.
Did I miss something else in configuring AD authentication ?
If so what because the guide I followed was straight-forward and has no mention of using the built-in database users. I am not sure either if my permissions will be linked to my AD group ( my AD user is not in Admin group).
I am also not sure on whether Jenkins continues supporting login with the admin user after you have enabled AD authentication.
So this will come down to you Authorization Plugin and what you have setup there.
If you are using the Role Based Strategy and haven't granted your user Admin permissions then it is correct for you have not got them.
When setting up the Active Directory Plugin in the Advanced menu there is an option for Use Jenkins Internal Database which allows
This option allows to fallback into the Jenkins Internal User Database for the specific user selected (ONLY ONE USER).
You could select this option and set your built in user (or admin) as the fallback.
If you are currently totally locked out you can edit the config.xml and set <useSecurity> to false and restart the Jenkins process which will remove the Active Directory config
I am trying to configure a project-based authorization matrix in Jenkins. All of the users are authenticated through the SAML 2.0 plugin which is functioning as expected. Users are added to an Active Directory group to get access to the server, and then assigned permissions using the matrix. What I would like to do, is have the Authenticated Users group serve as a baseline for what all logged in users are permitted to do, and then grant administrative access to a few Active Directory users who will have Admin privileges. However, only 2 out of the 8 users granted Admin privileges in the Matrix (underlined in blue) are able to see the "Manage Jenkins" button in their portal, while the other 6 users (underlined in red) are unable to see Manage Jenkins. All 8 users are in the same AD group and there are no discernible differences among these 8 users. auth matrix
Jenkins version is 2.289.1 running on Red Hat Enterprise Linux
I figured out the that the problem was with Jenkins' config.xml file which Jenkins uses to configure global security. Some users were stored in the format "Firstname, Lastname", while others were stored as their email address. In the Jenkins UI, it will display users as "Firstname, Lastname", but it uses the email address to identify them on the back end. I manually edited the file and replaced all of the user's names with their email addresses. I then ran sudo systemctl restart jenkins and allowed me to assign permissions to those users.
I am running Jenkins within Tomcat 7.
I want to log in and operate Jenkins securely over the web.
I set up an admin user and password. Logging in with these credentials works fine initially.
Then, after a while, I try to log in but submitting my login request just sends me back to the login screen (but without the "Invalid login information. Please try again." message).
I have to hack around it by disabling security in config.xml, and re-enabling it via the "Configure Global Security" page. I've tried two different Security Realms: "Jenkins’ own user database" and "Unix user/group database". They both work initially then eventually fail.
My jenkins have configured to use OpenID SSO to login.
My question is how to use a Jenkins normal user to login without changing the Security Realm from OpenID SSO to Jenkins’ own user database.
By saying Jenkins normal user, I mean those who signs up from the jenkins signup page: http://your_jenkins_url/signup
This isn't easily possible.
As mentioned in this related answer, the easiest solution would be to add this extra user to your SSO system.
Alternatively, as the other non-accepted answer there mentions, along with this mailing list thread, you could look into setting up PAM authentication, as that would let you delegate to multiple authentication schemes.
I do not want new users to be able to sign up. So in Jenkin's Configuration, I disabled "Allow users to sign up" with using Jenkin's own user database.
But how can I manually add users now?
Also, is there a default admin user I should take care of?
There is "Create Users" in "Manage Jenkins".
In case "Allow users to sign up" was already disabled and security turned on and there is no user you can use to login the only way to go is to change Jenkins configuration manually on the server and restart server.
Thing to change is in Jenkins Home folder i config.xml file.
change
<useSecurity>true</useSecurity>
to
<useSecurity>false</useSecurity>
restart and refresh browser
Voila!!!
Manage Jenkins -> Jenkins own user database, Anyone can do anything. Then you are not forced to login or signup. Manage Jenkins -> Manage Users and you create your users, then setup security accordingly.
If you don't setup the security method first there is no way to add users.
A convenient way for configuring Jenkins is to edit the config.xml file directly and use the Manage Jenkins -> Reload configuration from Disk hyperlink instead of restarting the service.
The recommended way to handle this is to use matrix based security and leave sign up on. Set default permissions to nothing, this way when people sign up they can't actually do anything until you explicitly grant them permissions. If you don't want to leave the sign up on for some reason, you will have to enable to add users and then disable when you are done. As far as I know there is no way to add a user with sign up turned off unless you want to hand edit the config files.
There is no default admin user, you will want to make sure you add yourself with max permissions or you risk getting locked out when you enable security.
