Hi Rick,

If it's not only the test connection that is failing, in case the directory synchronization is also not working, It can be also related to the issue described in this KB article.

Hi Rick,

I susepct that you are facing the bug described here: https://jira.atlassian.com/browse/JRA-27347

If that is the case then it is just the test that fails, but the LDAPS connection and the synchronisation are actually successful. Therefore I would suggest you start by checking whether the connection and synchronisation are working correctly, rather than just following the error message, and if they aren't then I would suggest that you open a support ticket so that we can investigate the cause of this issue.

All the best,
John
