Windows Authentication

Hi every body …

I am in develop a web application … and I want to read a “Windows Authentication” I use PHP with apache and the saved data in LDAP

my question … how can user auto login such as “sharepoint” without write username & password (read it automatic)

many thanks for any help or link to understand how to make that

You need to look at $_COOKIE (http://www.php.net/manual/en/reserved.variables.cookies.php) which allow you to store data and recall it for auto-login type things.

Be careful on security and make sure that any stored data is hashed.
