Access is denied Jenkins - jenkins

Here I am trying to open my Jenkins and having this error
Please, mention I am a junior developer and trying to learn Jenkins. I installed Jenkins on my mac with this link and install Matrix Authorization Strategy plug in. Then I changed somethings then pressed save. Boom. Access is denied. Please, help me. I tried to uninstall and install again but still the same thing. Access is denied. Please, help me with this issue. I use mac.

When Matrix Authorization Strategy is enabled, you need to grant privileges to the users, too.
Login into Jenkins with an user with admin privileges, then go to the authorization configuration:
Manage Jenkins -> Configure Global Security -> Authorization
In the User/Group table, grant the necessary rights to the users.
For example: "Overall Read" for all authenticated users, etc.
If you don't have access to an admin account, edit the Jenkins server configuration file config.xml in the Jenkins home, setting:
<authorizationStrategy class="hudson.security.FullControlOnceLoggedInAuthorizationStrategy">
<denyAnonymousReadAccess>true</denyAnonymousReadAccess>
</authorizationStrategy>
Then, restart, login and fix the configuration.

How to login to jenkins when LDAP server is not available?

I did setup jenkins with LDAP and i'm able to login. But when i stop the LDAP server I'm unable to login to jenkins using jenkin's local user account. Also always editing the config.xml is not a good idea to change security settings. Please help me.
What Ive done in a previous role - is a copy of Jenkins config that allows admin & a selection of other users access when LDAP is down.
When LDAP is down , I switch manually
mv config.xml config.ldap.xml
mv config.internal.xml config.xml
Restart Jenkins ( https://stackoverflow.com/a/8077830/1935094 )
The config.internal.xml was setup before I configured LDAP. You could also backup your config.xml , configure Jenkins for internal user access , copy that off and copy back in your LDAP configured config.xml.
Anyway - the idea is that you can still get in , run jobs etc until LDAP is back.
Ive had thoughts about automating it , if LDAP is detected as down ( you could run a lookup periodically , then switch if need be...
As of now, local user login is not possible when LDAP enabled. Jenkins internal user database is automatically disabled when you activate LDAP authentication.
Few Jenkins JIRA to get more details on this.
JENKINS-3404
JENKINS-29162
There is no other way except editing ~.jenkins/config.xml.
Better option is to migrate(LDAP user) to Jenkins own user database.
FOR FUTURE:
- Add a secondary LDAP server on Jenkins host.
- Remember to check "Ignore if unavailable" on the first LDAP.

How to get jenkins-cli work without granting any permissions to "anonymous"

I am using Jenkins version 2.89.2.
I have Role-based strategy enabled for authorization. Anonymous has not been granted any rights. I have some jobs being triggered remotely using the Jenkins cli. This used to work well when I was using an older version of Jenkins but once I moved to this version I am not able to get this working without granting Anonymous user build/job permissions.
In order to get this working without any permissions granted to Anonymous user, I tried to have a user whose ssh public key is updated in the Jenkins web ui (user configuration).
With this setup, when I try to use Jenkins-cli.jar as below, I get an error: ERROR: No such job 'testing'
java -jar jenkins-cli.jar -s http://<servername>:<port>/
-i /user/jen/.ssh/id_rsa build "testing"
While searching around the internet, I saw that we can make this work by granting the "Anonymous user" read permission, I did that too but with that when I try to run the jerkins-cli jar (same command as above) I get the error: ERROR: anonymous is missing the Job/Build permission
I do not want to grant anonymous user Job/Build permissions.
Any ideas/thoughts to fix this please ?

Change/Set password for git system account on omnibus gitlab server

We installed gitlab in omnibus method.We are using gitlab-rake console for lot of our administration activity.If it is a one time activity we can get root access and do our activity as sudo.In case of permanent scheduled operation we are facing problem with root access.
As per company policy no one can have permanent root access.
We know we can run gitlab-rake console via git system user but in omnibus method git account is password less.
[root#host:/etc]# grep git /etc/shadow
git:!!:16904::::::
gitlab-www:!!:16904::::::
gitlab-redis:!!:16904::::::
gitlab-psql:!!:16904::::::
if we set password to git or gitlab-www or gitlab-psql , we were able to login as that account and able to proceed with the show.
But my issue is what could be the impact on gitlab if we change/set password to this account.
Will it impact gitlab infrastructure?
Will it create any problem?
Will it affect the gitlab performance?
Will it affect the gitlab functionality?
Please help us.

Remote Access to Secured Jenkins Server

I have a Jenkins installation on a machine running Windows Server 2008. The Jenkins installation is secured using Jenkins own user database with matrix-based security authorization. Anonymous users don't have any access, except to register an account. I have set up an account and gave this account full access.
Now I'd like to trigger a build remotely from a different machine that hosts the repository. I believe this should be possible by accessing the following URL:
https://[username]:[user_api_token]#[address.of.jenkins]:8080/job/[project]/build?token=[project_api_token]
However, this does not seem to be working for me. When I access this site in a browser, Jenkins forwards to the login-page, and does not start the build.
What am I doing wrong? It seems to be an authentication problem, as I'm not logged in after opening the URL above. Furthermore, if I give anonymous users full access, the URL works.
Try invoking the build from a command-line program like curl:
curl http://[userid]:[user_token]#localhost:8080/job/[project]/build?token=[proj_token]
or
curl --user [userid]:[user_token] http://localhost:8080/job/[project]/build?token=[proj_token]
I think your issue could be browser related, embedding credentials within the URL (Firefox pops up a warning in my case telling me I'm about to login to Jenkins)
