How can I add a limited access account for jenkins automation when I'm using Global GitHub OAuth Settings?
I'm using GitHub OAth for login to jenkins and I have python jenkinsapi scripts that I want to run as a user with read only access. At present, all my users are github users.
I can create a github account without access to my repositories and then limit that accounts access to jenkins but this seems cumbersome.
Is there a way to use multiple security realms or to create local users?
It seems that when jenkins contains a local user, that the plugin uses this first (plugin-source)
If you look at Manage Jenkins->Configure Global Security, you can see that you can select only one security realm.
I would say, for Jenkins use create a github service account specifically that user can be restricted to just a few repositories. You can also look at matrix based security or project based matrix security if you want to restrict authorization further

I've got Artifactory set up to allow SSO via an OIDC client in Keycloak. Keycloak talks to Active Directory in the background. I've also got the same Active Directory configured within Artifactory. I've also configured Keycloak to provide user groups in the userinfo structure.
What I'm trying to do is to get OAuth users to automatically be added to the imported LDAP groups within Artifactory. I don't mind if this is done via the userinfo structure or via a separate LDAP lookup when a user logs in. However I can't seem to figure out how to achieve this.
I know that Artifactory provides a plugin called synchronizeLdapGroups.groovy, which seems to advertise doing what I need, however it seems like the plugin is not actually taking effect. That is to say, users do not end up with the permissions that being in the LDAP groups would provide.
I've attempted to write a plugin myself to do what I need, but when I make the API call to add the groups to the user, the plugin crashes. It's unclear why at this point.
It seems like others have used the SCIM feature in Artifactory for something akin to this (mostly via SAML rather than OIDC though), however Keycloak doesn't support SCIM out of the box and the SCIM plugin I've tried using has similarly given me no results.
Has anyone done something similar to this, and has a working solution I could follow?
If it's a specific group you want all users to be in you could try:
Under Security - OAuth SSO settings tab - check "Auto Create Users"
Under Identity and Access - Groups - select the specific group and check "Automatically Join New Users To The Group"
I'm guessing you want to automatically sync user-group association between Keycloak and Artifactory. SCIM is what you're looking for but there's a known issue specifically with Keycloak SCIM plugin.
We're looking into the SCIM plugin for Keycloak (can't commit on a specific timeline for a fix but it should be sometime this quarter).
If you only need the association in the UI you could try SAML with "Auto associate groups" set. It won't apply the groups association for APIKey/Token calls but it would work for the UI.
EDIT:
after further investigation github.com/Captain-P-Goldfish/scim-for-keycloak isn't relevant here - it makes keycloak a SCIM client, not a SCIM server. There's no official support of SCIM in keycloak, see issues.redhat.com/browse/KEYCLOAK-2537 . and there's no working plugin for keycloak that makes it a SCIM server that I could find (tried a few, all broken). For now Artifactory can't support SCIM with Keycloak
We have Jenkins setup in our organisation with two organisational folders which basically does builds for repo's from two different github organizations.
We use Keycloak to authenticate to Jenkins. (Not sure if that's relevant or not) and we authenticate using openid connect with Keycloak.
I would like to know if it is possible to restrict access for a certain group of users to only be able to view builds on one of the github organizations. So for example if we have two github organizations: mrrobot_org and evilcorp_org, then I would like to be able to make an evilcorp_org_devs_group and add users to that group which would then restrict those developers from only accesing builds from the evilcorp_org github organization.
Someone told me this might be possible to do from Keycloak, but it does not seem likely.
I've tried quite a few things already but from what I've read the best option seems to use this plugin
https://plugins.jenkins.io/role-strategy/
and match the organzation using a regex to match a folder:"Folders can be matched using expressions like
^foo/bar.*".
Any other suggestions how I could do this?
Thanks so much.
For anyone reading this. I ended up using the Folder auth plugin for Jenkins.
I ended up sticking to Keycloak for Authentication, but used the folder auth plugin for Authorization.
So this allows me to restrict access per Jenkins folder. Each folder containing the builds of a given github organization.
The plugin is pretty easy to use. You can check it out here:
https://github.com/jenkinsci/folder-auth-plugin
The docs are here:

What is the benefit of implementing Active Directory based Security to servers like Jenkins?
The only benefit I can think is the admin of the sever does not need to add/remove users because user can login themselves using AD credential.
But In my case I do not want to have the whole company access my server. the server is only used by my team. How can I disable the whole company from login in. (case1)
Besides, I want to grant different permissions to different members in my team. The new members get less permission, the experienced team members get more permissions. I believe this is very common. But using Active Directory based Security looks like they get the same permission because they are in the same groups (case2)
So why should I use Active Directory based Security? Can I resolve the above two cases in a server configured with Active Directory based Security?
Some corporate environments make this a security requirement. In said environments they usually have an internal request system where users can request they have their credentials added to an appropriate group for access to Jenkins. This is better than Jenkins own database and having them email you, the Jenkins administrator.
Once AD Authentication is configured in Jenkins and appropriate groups created in AD you can do a one-time setup of those groups with the Role-Based Strategy plugin in Jenkins and define what those groups have authorization to do.
Plan your groups well and it is a function that you will no longer have to worry about.
Warning: Be very careful when switching over from Jenkins own database user authentication to AD authentication. If you don't get the BindDN details just right you can get locked out.
I am learning Jenkins and i am using version 1.605. I am learning about setting security options in jenkins. I found below options in jenkins configure global security page under the security realms:-
Delegate to servlet container
Jenkins'own user database
LDAP
I want to understand in which scenario, which option should be used?Please help me understand.
The "servlet container" refers to the web server that you are using to host Jenkins, typically Tomcat. The configuration file $CATALINA_BASE/conf/tomcat-users.xml may already be set up and managed by your organization. In this case: "why reinvent the wheel?". Use this if your organization already has a process that manages the Tomcat users configuration. This is also probably the most archaic solution.
The "own user database" is just what it sound like. Instead of relying on something else, Jenkins keeps it's own database of users. You can create and delete users through the Jenkins UI. You can even let new users sign up right from UI. If you don't know what to use, use this one. It's simple and self-contained.
The "LDAP" provides integration with LDAP/ Windows Active Directory. If you are in a corporate/small business environment that already utilizes LDAP for maintaining users and groups, it will be very beneficial to hook into that and off-load user management to the IT team that manages LDAP/AD. Note that unless you are that IT admin, you will need to contact the said admins for connection information/credentials to the LDAP/AD
Slav did a very clear answer.
If you choose the option 2 or 3, you can use the Role Stragegy plugin to create application roles and assign roles to Jenkins users, LDAP users or LDAP static/virtual groups.
If you have a lot of users, this plugin can save your life to assign permissions :)
I am using access control on Jenkins with openid plugin. Users are authenticated through Google account.
But i also need to have users created on Jenkins internally. i.e role based access control.
Is there a way to configure Jenkins to make it possible to use multiple access control mechanisms at the same time ? Currently i can only select one.
Any plugins to make it possible ?
No, your users need a google apps account to login.
But that shouldn't be a problem with https://wiki.jenkins-ci.org/display/JENKINS/Role+Strategy+Plugin
