Description:
------------
Using : 
INGRES_EXT_VERSION : 1.2.1 INGRES_API_VERSION : 4
version.rel on client (web server) : II 3.0.2 (su9.us5/109)
version.rel on ingres server  machine : II 2.5/0011 (su4.us5/00) 8908
php : PHP Version 5.1.2 (and not 5.1.1 as I could not give 5.1.2 in the php_version field of this form)

Description :
ingres_connect() doesn't work with 4 parameters :
when giving 3 parameters ($base, $user, pass) it works fine;
if, with the 3 same parameters, I add a 4th one, $options, an array which is previously given, I get an error.



Reproduce code:
---------------
$options = array("date_format" => INGRES_DATE_MULTINATIONAL4 );
ingres_connect($base, $user, pass, $options);
I get the following error :
Warning: ingres_connect() [function.ingres-connect]: Ingres error : 6399 : User authorization check failed. Your user identifier was not known to this installation. Contact your system manager for further assistance. in /usr/.../table.php on line 22
Warning: ingres_connect() [function.ingres-connect]: Ingres SQLSTATE : 5000H in /usr/..../table.php on line 22 

Expected result:
----------------
no error
