I need to be able to authenticate for a PHP-based service using an exteal server ruing Zimbra 8.6. I have been trying to figure out a way to do that, and it seems the general approach is to use SoAP based queries. I am not conversant with SoAP, I know that LDAP is a normal service and I may be able to directly bind to the port and authenticate like with any other LDAP service using php-ldap on client.
Though I was able to find PHP wrappers for the same, they provide more capabilities and for reasons of security, I do not wish to enable them, instead using the LDAP service directly as only authentication is required. (This also makes a few things easy from firewall point of view.) Also I see (from various solutions on web) that the SoAP versions change between releases. Does this approach work with ZCS, if so is it preferable?
