Description

We are configuring Cerebro to autheticate users by LDAP on Active directory, but authetication fails with: Caused by: javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

we tried to disable certification validation with these parameters in application.conf: play.ws.ssl.loose.allowWeakCiphers = true play.ws.ssl.loose.allowWeakProtocols = true play.ws.ssl.loose.acceptAnyCertificate = true play.ws.ssl.loose.disableHostnameVerification = true

Cerebro continues to check certificate and fails authentcation.

we tried to debug problem by play.ws.ssl.debug.all = true but cerebro fails to start

Any idea?

Research direction
Investigate how Cerebro's LDAP authentication module handles SSL configuration. Look at the Play framework SSL settings in application.conf, particularly whether the loose settings are being overridden or ignored. Check the LDAP authentication code for certificate validation logic. Search for similar issues or commits related to SSL configuration. Examine the conf/application.conf file for any missing or conflicting settings.
