(PHP 4, PHP 5)
ldap_connect — Connect to an LDAP server
$hostname = NULL
[, int $port = 389
]] )
Establishes a connection to a LDAP server on a specified
hostname and port.
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/.
port
The port to connect to. Not used when using URLs.
Returns a positive LDAP link identifier on success, or FALSE on error.
When OpenLDAP 2.x.x is used, ldap_connect() 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().
If no arguments are specified then the link identifier of the already opened link will be returned.
