Jenkins - can't see "Manage Jenkins" option - jenkins

Question

I've just installed the latest version of Jenkins and enabled the so-called "Project-based Matrix Authorization Strategy".
I have added a few users with all privileges and some of them can see the "Manage Jenkins" option after logging into Jenkins, but there are people who can log in but can't see this option.
Really strange behavior. I have checked the configuration in jenkins.xml but it seems ok. Do you have any idea what can be an issue?
Thank you for any suggestions,

Answer 1

Try using the link https://<JENKINS_URL>:8080/manage loaded the Manage Jenkins option on the UI.
OS: CentOS
Java Version: 1.8

Answer 2

It seems the permissions in config.xml are case-sensitive. So when there is such an entry :
<permission>hudson.model.Item.Build:mysuperuserlogin</permission>
and you log using LDAP authentication and this variant of password MySuperUserLogin, you will be able to log in successfully but you won't be able to use the permission.

Looks like your authorizationStrategy has been updated
Step 1: Go to your config.xml file and open this to any editor
sudo vim /var/lib/jenkins/config.xml
Step 2: Search authorizationStrategy tag inside xml file and change the value to
<authorizationStrategy class="hudson.security.FullControlOnceLoggedInAuthorizationStrategy">
Step 3: Restart Jenkins:
sudo systemctl restart jenkins
Try to log in now!
Here is the default xml file of Jenkins you can crosscheck your other configurations
