Setup LS with auth_webserver = true, auth_webserver_autocreate_user = true, and define a hook function 'hook_get_auth_webserver_profile'.

The hook function is not properly called:

Line 92 of UserIdentity.php (in context):

            if (function_exists("hook_get_auth_webserver_profile"))
            {
                // If defined this function returns an array
                // describing the defaukt profile for this user
                $aUserProfile = hook_get_autouserprofile($sUser);
            }

It should be:
if (function_exists("hook_get_auth_webserver_profile"))
{
// If defined this function returns an array
// describing the defaukt profile for this user
$aUserProfile = hook_get_auth_webserver_profile($sUser);
}
