ldap_connect - Connect to an LDAP server

SYNOPSIS

       resource ldap_connect NULL ([string  $hostname], [int  $port = 389])

DESCRIPTION

	Establishes a connection to a LDAP server on a specified $hostname and $port.

PARAMETERS

	      o $hostname
		- If you are using OpenLDAP 2.x.x you can specify a URL instead of the hostname. To use LDAP with SSL, compile OpenLDAP 2.x.x with
		SSL support, configure PHP with SSL, and set this parameter as ldaps://hostname/.

	      o $port
		- The port to connect to. Not used when using URLs.

RETURN VALUES

	Returns a positive LDAP link identifier on success, or FALSE on error. When OpenLDAP 2.x.x is used, ldap_connect(3) will always  return  a
       resource  as it does not actually connect but just initializes the connecting parameters. The actual connect happens with the next calls to
       ldap_* funcs, usually with ldap_bind(3).

	If no arguments are specified then the link identifier of the already opened link will be returned.
