I have developed a site for our Company's intranet purpose, and it is set as home page. It is built with Joomla 1.5 on wamp server. Now i want to site windows authentication using LDAP plugin. But when i am enabling it, total site is becoming blank, I have also tried with the specifications given by simcfc73 but none worked out. I will be very thankful, if any one can solve this issue. Thanks, mkd
