This Plugin allows administrators to restrict user login based on user roles. This is useful e.g. when you want anyone to register on your site but you do only want certain people (e.g. editors) to enter the logged in area.
Roles that are allowed to log in are set in a new menu entry in the Users menu.

There are a lot of really well done, inclusive membership plugins out there… but sometimes they are overkill. Simple Members Area 
allows you to setup a section of your site that logged in users can access in a matter of minutes.
The premise is simple, you create your “members area” by creating pages and saving them as “private.” Then you can choose which 
private page your members should be redirected to upon login. Conceivably this page would have links to your other private pages 
(if there are any.)
With this plugin you can have a default landing page or have a specific page for each user as well.
