Notes from a conversation between Marc Laporte & Peter Baldwin

Peter wrote: The Thunderbird on my Fedora system only supported TLS on port 389, but not SSL on port 636. Wah? It's 2014! The only way I could get Thunderbird to work was using an unencrypted connection (which is disabled in ClearOS by default).

In /etc/sysconfig/ldap, uncomment and configure the following parameter:


Change the IP to whatever IP is needed for and then restart LDAP:

service slapd restart

2014-03-03: Marc confirms this worked.

And later Peter wrote: “After implementing SSL certificates in OpenLDAP properly (this too will be a ClearOS update), Thunderbird was able to connect to the LDAP server using SSL.”
