Thread:Extension talk:LDAP Authentication/why is it "Doing an anonymous bind" instead of using the username and password i entered?/reply (4)

It's doing an anonymous bind because the plugin is configured to search (for your user's DN) before bind. With LDAP calls, it's required to use a bind DN. The extension has no way of knowing what your DN is, so it needs to search for it, then use it to bind. Since you didn't provide proxyagent credentials, it must do an anonymous bind.

Please look at the configuration examples for Active Directory. They show how to do a straight bind with formats like USER-NAME@ and \\USER-NAME.
