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
- 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
