How to solve LDAP Error code : 10400

[Sai176]

Hi ,

We have recently cloned our sub-production instance with our production instance.

We are trying to test the LDAP server connection on both the instances and it throws the following error while testing the LDAP server:

" LDAP Server: Asia Pacific Domain URL: ldaps://<ldap server url>/ failed scheduled connection test. ErrorCode: 10400. ErrorMessage: sun.security.validator.ValidatorException: PKIX path building failed: java.security.cert.CertPathBuilderException: No issuer certificate for certificate in certification path found. "

Below is the screenshot of the same:

Upon checking the error code 10400 in ServiceNow, we found that it an exception in LDAP_ERROR_SSL_EXCEPTION. The certificate still has validity and is not expired.

We found a source in hi-portal (https://hi.service-now.com/kb_view.do?sysparm_article=KB0687792) but it didn't come to our help.

Request you to kindly help me with this.

Thanks&Regards,

Sai

Hi Sai,

Are you using LDAPs with Certificates; if yes then are those certificates valid for that instance. check that or re-configure that and test once the connection

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks
