Hi, I’m a trainee network administrator for a company. I set up LDAP authentication with the plugin for Jenkins without any problem.
Then I wanted to set up LDAPS authentication.
My first error was that I hadn’t put the certificate in the keystore.
To fix the error I used keytool with the following command: sudo keytool -importcert -file certificate.crt -keystore /usr/lib/jvm/java-17-openjdk-amd64/lib/security/cacerts -alias "certificate"
But now I’m faced with the error :
Unable to connect to ldaps://:636 : javax.naming.CommunicationException: :636 [Root exception is javax.net.ssl.SSLException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty]
My environment is as follows:
a virtual machine running Ubuntu 24.04 LTS with apache, jenkins, ownCloud and Subversion
a physical Windows Server 2022 machine, where I access Jenkins
When troubleshooting these issues, I like to use the SSLPoke tool at GitHub - rksk/SSLPoke: Java tool for testing validity (certificates) of trust stores
That way you can confirm if it’s an SSL issue / cert issue or a Jenkins configuration issue.
Then, I think the proper modern way of managing the cacerts is the use a jks file and pass it as an argument when starting Jenkins
Finally, you may want to use Jenkins official docker image to help with reproducibility / isolation of the whole setup.
if you investigation points to a Jenkins config issue, could you post the relevant section of the Jenkins config file ?

I try Java tool for testing validity (certificates) of trust stores java -Djavax.net.ssl.trustStore=/usr/lib/jvm/java-17-openjdk-amd64/lib/security/cacerts SSLPoke <domain name of the ldap server> 636
And i got this error :
Erreur : impossible de trouver ou de charger la classe principale SSLPoke
Causé par : java.lang.ClassNotFoundException: SSLPoke
Traduction :
Error : unable to find or load the SSLPoke main class
Caused by: java.lang.ClassNotFoundException: SSLPoke
I think in your case you want to make sure the SSL connection from your Jenkins server to your LDAPs is working fine, so use your LDAP server. Don’t forget to adjust your port. You probably want to test 636 and 3269
To compile the tool, make sure you have the JDK installed, open a terminal in the folder of the SSLPoke.java, and run ‘javac SSLPoke.java’
This will generate a SSLPoke.class, and then you can use java SSLPoke to execute it
