To connect to Zimbra LDAP externally:

Enable access to server via network firewall (OR Cloud firewall)

Enable access to port 389 of Zimbra server via firewalld:

firewall-cmd --zone=public --add-port=389/tcp --permanent
firewall-cmd --reload

Then test connectivity to Zimbra LDAP via:
```
ldapsearch -x -h <email-server-fqdn-or-ip>:389 -b 'dc=example,dc=com' -D 'uid=saurabh,ou=people,dc=example,dc=com' -W dn,mail
```
In above replace username saurabh and domain example.com appropriately. Zimbra LDAP will require authentication for the DN specified with -D, without which it does not responds to ldap queries
1. In case of confusion on Zimbra LDAP structure we can use:
```
su - zimbra
/opt/zimbra/libexec/zmslapcat -c /tmp
vim /tmp/ldap.bak
```
  See CentOS 7.x Zimbra backup and restore
2. For filters while connecting to Zimbra. See
  - CentOS 7.x Zimbra GALsync between two Zimbra servers
  - CentOS 7.x Use LDAP address-book in thunderbird
