Confirm that the SSL Cert is indeed correctly imported. To verify make sure the steps below were followed.
(Example uses CA Directory).
Note: In this example the Java is version jdk1.7.0_75 and the JAVA_HOME is set to C:\Program Files\Java\jdk1.7.0_75\jre
Navigate to the follow directory:
Example Certificate in PEM format: corporateuserstore.pem
Open up CMD as administrator.
cd C:\Program Files\Java\jdk1.7.0_75\bin
Stop application server
keytool -keystore "C:\Program Files\Java\jdk1.7.0_75\jre\lib\security\cacerts" -import -file "C:\Program Files\CA\Directory\dxserver\config\ssld\personalities\corporateuserstore.pem" -trustcacerts -alias CADIRTrusted
Verify that the connection was switched to a secure connection. This will throw an error if it isn't switched. To do this on a new creation - Go to IM Management Console > Home › Directories › New Directory > Enter in proper environment credentials and name > Make sure to check off "Secure Connection" > Click Next.
If it is an old directory you need to export the directory.xml and update the field "secure" to "true".
Once updated save it and import the directory.xml file. Be sure to keep a backup of the file.
