NullPointerException when using "Test LDAP settings" button (regression in 2.342)

    XMLWordPrintable

Details

    • Bug
    • Status: Open (View Workflow)
    • Minor
    • Resolution: Unresolved
    • ldap-plugin
    • Tested on 2.346 and 2.346.3
      LDAP plugin version 2.10 and 2.12

    Description

      Using Test LDAP settings button is rising an NPE. LDAP configuration still works after save, it's just the test that has an issue.

       

      Tested with local LDAP based on docker image of https://github.com/rroemhild/docker-test-openldap

      Reproduction step:

      • Run a Jenkins instance 2.346+
      • go to Manage Jenkins > Configure Global Security
      • select security realm = LDAP
      • Configure LDAP
      • Test LDAP with one user, for example professor/professor
