I've istalled limesurvey web application on windows server 2008 - with IIS_7.0.60000.16386,I use PHP 5.2 and Active directory.

I've configured ldap extensions and Active directory is installed and it works fine maybe i have some problems with "CONFIG-LDAP.PHP" file, i suppose,
infact when i perform token management\LDAP-Import from an Inactive Surveys I get the error message : "UPLOADING LDAP QUERY ERROR: Can't Bind to the LDAP directory"

ps. I've selected the ldap query (from drop down listbox): "Administrator group".
can you please... help me??
