I had a problem this week due to recent updates for DST. LDAP over SSL stopped working. It took me a fair amount of time to track down the answer, so I figured I would share.
Basically, the secure certificates store is tied to the JVM, not to ColdFusion or even JRUN. So when you update the JVM you lose a bunch of Certificate Authorities in your keystore (I assume since the file is so much smaller) and you lose any custom Certificate Authorities you may have added.
I found the solution at via a Google search at sagewire.org (JVM upgrade breaks secure CFLDAP connections), but basically the solution is to copy your former copy of the cacerts files to the new JVM’s location, then restart ColdFusion.
