About LDAP and access control

-- YangCheng - 07 Sep 2016

Hi, i've installed `LdapContrib`, `LdapNgPlugin` `NewUserPlugin`, But meet some problems.

Currently, User login ahthenticated by my Ldap server is down and works well. But:

1. After i installed LdapNgPlugin, I always get red exclamation mark in `configuration->extensions->enable or disable installed extensions`, but within this tab, i can't see anything wrong. Configuration is already set

$Foswiki::cfg{Plugins}{LdapNgPlugin}{Enabled} = 1;
$Foswiki::cfg{Plugins}{LdapNgPlugin}{Module} = 'Foswiki::Plugins::LdapNgPlugin';

2. How can i do access control for the users loggin from LDAP? I can't see those users or gourps in `Main/WikiUsers` or `Main/WikiGroups`. So how can i do access control? for example, if i don't want a user to view a page, what should i set in `Set ALLOWWEBVIEW = ???`

3. Even i installed NewUserPlugin , but /Main/$WikiName topic still doesn't exists, how to automatically create this topic when a user login?
