LDAP error "unable to find valid certification path"

I am trying to get Jenkins to make a LDAPS lookup on server.
With this “ldaps://DKSGDx.txxx.xxx”
But I get keep this error
[Root exception is javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target]

I have tried to import the certificate. Like described in
https://community.progress.com/s/article/LDAPS-authentication-fails-due-to-javax-net-ssl-SSLHandshakeException
and
https://community.bmc.com/s/article/AMA1210-How-can-I-import-a-SSL-certificate-into-the-Java-Truststore-to-have-Jenkins-use-it-to-connect-to-the-Mainframe

But still the same error, watt can I do now t debug the issue

Hello @MortenRick and welcome to this community. :wave:

The error message you’re seeing seems to indicate that the Java runtime environment used by Jenkins does not trust the SSL certificate presented by the LDAPS server. :thinking:
This can happen if the certificate is self-signed, or if it’s issued by a certificate authority that’s not included in the default Java truststore.

Thanks @poddingue I added the AD server certificate to the Java truststore, then it works
