LDAPS with Community Edition

Hi,
is it possible to use LDAPS with the Community Edition?
If I switch in the ccnet.conf from ldap://ldap.example.com to ldaps://ldap.example.com:636 and restart the server, the LDAP query no longer works.
I have already installed a valid certificate on the Ubuntu server and the website can be accessed via HTTPS.

Thanks
Juergen
