I am currently running Jenkins 2.462.3 with Java 17.0.13 on Windows Server 2022 (core mode). I utilize the LDAP module for authentication. Up until this most recent Jenkins upgrade (version 2.479.2), I’ve had no issues upgrading Plugins and Jenkins via the web interface.
After going through the upgrade thread, I read you need to update LDAP plugin first. So that is what I did below (however, I have errors now).
- Stopped Jenkins (
Stop-Service Jenkins). - Downloaded/copied
ldap.hpi(version733.vd3700c27b_043) to the following folder (renaming it toldap.jpi):
C:\Users\jenkins-sa\AppData\Local\Jenkins\.jenkins\plugins\ - Started Jenkins again (
Start-Service Jenkins).
Upon visiting the page after the service start, I get the following error message. What am I doing wrong? Permissions on the file are exactly the same as the previous file (Administrators, SYSTEM, and jenkins-sa have Full Control).
