since upgrade, unable to find valid certification path to requested target. ldap bind failed
Hello. We have encountered an issue with Pega failing to bind to LDAP in a previously working environment since we upgraded from 7.3 to 8.3. Getting the error below in log. The only change is to Pega, no Tomcat or O/S changes. We confirmed the userid/pass is correct. No changes to Pega keystore file – in fact they imported the key from a working environment as part of troubleshooting. The Test connectivity tab also does not return successful. Any suggestions? Thanks in advance.
