Topic: How can I force LDAP to accept only connections secured over STARTTLS

==== Required information ====
- iRedMail version (check /etc/iredmail-release): 0.8.7
- Linux/BSD distribution name and version: Ubuntu 14.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP

I want to enable access to my LDAP installed by iRedMail to another server. Therefor I want to be sure that every connection is encrypted by StartTLS. I've found a tutorial which explains howto secure LDAP by STARTTLS and howto enforce a connection over STARTTLS. Can this be done as well for the LDAP installed by iRedMail? And what would I have to do?

Thanks in advance!

I didn't find such parameter. You'd better ask in OpenLDAP mailing list instead.

Re: How can I force LDAP to accept only connections secured over STARTTLS

One possible solution is: don't configure your OpenLDAP to listen on ldap://. Instead, just listen on ldaps:// (it uses port 636 instead, not 389).
