Setting up firewallD on Centos 7 servers. They use LDAP for authentication over SSH login. Do I need to explicitly allow port 389 LDAP on the default zone on FirewallD or because iv allowed SSH and the server will connect outbound to LDAP initially, will this not be required for the return inbound connection?
Im not very familiar with LDAP. I suppose it would be possible that the server connecting to LDAP server will only need to read the LDAP directory and the LDAP server wont need to send over any data on port 389?
