Hi.

I have a problem trying to connect Thunderbird or Outllok with ldap, I followed all the steps in the different tutorials. My system is fully functional. I have the ports open via firewall (ufw), but apparently the connection or some important port is still blocked.

Another detail is that if I try to telnet to port 389 or 636 it won't respond at all. As I have read in the documentation, these ports are closed by default, how should I open them so that they can be listened to from outside the network?

Another detail is that if I try to set the certificates in the configuration of the slapd.conf file (I use Let's Encrypt certificates), the ldap service gives an error and does not work.

What should I do?

Re: LDAP connection problems and other details.

Debian 10 uses nftables firewall, not ufw. You may need to update /etc/nftables.conf to open ports.
