Users are unable to authenticate

[Deepu Kurup]

From the logs :- I find this error :- 

Crowd user authentication fails with 'Directory 'X' is not functional during authentication' error

On Checking the LDAP test connection I get the following error :- 

There was a problem communicating with the LDAP server: simple bind failed: <Ixyz.com:3269>; nested exception is javax.naming.CommunicationException: simple bind failed: <Xyz.com> [Root exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed]

Need help asap

Welcome to the community. This is because your products are missing the intermediate(chain) certificate in the JDK cacerts file. Importing the chain certificate to the JDKs cacerts file will fix the issue. I faced a similar issue and it was fixed after importing the intermediate certs.
