I'm sorry but I can't find that config.xml file in my Windows 10 enterprise system. How exactly can I get to it?  I have ON the setting "Show Hidden Files and Folders".

It depends on how you are running Jenkins.

If you are running Jenkins from a command line using the war file, like:

    C:\Users\Mark\my-jenkins> java -jar jenkins.war

then the Jenkins HOME directory is placed in the ".jenkins" subdirectory of your home directory.  In my case, that means I have:

    C:\Users\Mark\.jenkins\config.xml

that contains the line '<useSecurity>true</useSecurity>'

If you are running Jenkins as configured with the MSI installer, then the file is:

    C:\Program Files (x86)\Jenkins\config.xml

If you've modified your installation by setting a value for JENKINS_HOME before starting Jenkins, then that is where it was placed.

If none of those match your installation, please describe in more detail how you have installed Jenkins on your Windows 10 machine.

Mark here is what I have in my "C:\MyJenkins\jenkins.exe.config" file.Here is what I have inside the file :

<configuration>

  <runtime>

    <generatePublisherEvidence enabled="false"/> 

  </runtime>

  <startup>

    <supportedRuntime version="v4.0" />

    <supportedRuntime version="v2.0.50727" />

  </startup>

</configuration>

Now should I put that <useSecurity></useSecurity> line in THIS file, and if so where?

The file jenkins.exe.config controls the way Windows executes the program "jenkins.exe".  It does not store the global Jenkins configuration.

The global Jenkins configuration (including the <useSecurity> setting) is stored in a file named "config.xml".  The file that needs to be modified is not named "jenkins.exe.config", it is named "config.xml".  

If you search your file system (Windows search, or with a find command) for a file which contains the text "<useSecurity>true</useSecurity>" and is named "config.xml", that is the file.  A file of any other name won't do.  Adding the text to any other file won't do.

All the best!

You need to restart the Jenkins service.

[Steve Burrus]

NOPE it  still didn't work. Even after re-starting the Jenkins service I STILL get the login area. I would appreciate your continuing help with this persistent problem.

[Slide]

Can you send a screenshot of the login area that you are seeing as well as attaching the config.xml file you found (after replacing any company or personal information) that you made the change to?

Ok, it looks like in current versions of Jenkins, you need to do a few more steps than just change useSecurity to false. Please take a look at this link (https://jenkins.io/doc/book/system-administration/security/#disabling-security) and follow the steps there. I recommend stopping the Jenkins service, editing the file and then starting it back up.

Boy Slide this problem is hanging on like a "tenacious bulldog". I did EVERYTHING you recommended that I do but I STILL got the login area. Do you feel like helping me some more?

I think you need <authorizationStrategy/>, not </authorizationStrategy>  (the slash should be at the end).

Your search tool may be refusing to index the location where the file is stored.  Try a different search technique.

Try the following from an Administrator Windows Command Prompt:

C:\> FINDSTR /L useSecurity "%ProgramFiles(x86)%"

If that doesn't work, you could try installing some other program that will search for strings or file names on your disc.

If you have multiple drives (C:, D:, etc.), you might check to see if Jenkins was installed on one of the other drives.

The https://www.howtogeek.com/99406/how-to-search-for-text-inside-of-any-file-using-windows-search/ page suggests that Windows search might be choosing to not index the xml configuration files.  If so, then it gives hints that may help you change that setting.
