Answer 1

Transmit a search request to the server and interpret the response. A search request (encapsulated in PHP by ldap_search) consists of the following at a minimum:
a base object (or base DN in some documentation): no objects superior to the base DN ail be considered of the search result
a search scope: one, subtree, or base: the depth of the search
a filter: used to filter (narrow) the result pool
requested attribues: this is where the LDAP client should put cn, displayName, and any other attributes needed for processing:

Before authenticating, store the values to be authenticate into session variables. If authentication success use the session values to display.
If authentication fails, clear the session values and try to submit the login form again.
Following is the sample code to assign the values into session variable in ZF2:
$session = new Container('base');
$this->session->offsetSet('username', $username);
and to get the session value:
$sesUserName = $this->session->offsetGet('username');
I hope this helps.
