ldap authentication error

Hello,

I'm trying to make a ldap query but I am getting a strange error.

Warning: ldap_bind() expects parameter 1 to be resource, null given in
home/user1/cgibin/test.php on line 10

Does anyone knows what this means.

This is the code :

$bind = ldap_bind($ds ,"cn=user,o=company","password");

I have ldap support in php.

[PHP Modules]

openssl
overload
pcre

Simple, the first argument in your call of ldap_bind had the value NULL,
it should be a resource instead.

Where does $ds get it's value?
