Enable LDAP SSL/TLS user authentification in Zabbix

By default Zabbix Web interface doesn't offer the SSL/TLS encryption option for the LDAP connector however the feature is available in the PHP code.

If you need to enable the startTLS feature, you will have to edit the PHP file manually :

Edit /usr/share/zabbix/include/classes/class.cldap.php on Zabbix Web server :

 vi /usr/share/zabbix/include/classes/class.cldap.php  

Search for the 'starttls' definition (line 44) and set the value to 'true' :

 'starttls' => true,  

Save the file and you're good to go !

Hope that helps !
