Content Access OG

'Content Access OG (Organic group)' allows administrator to set organic group based content permissions.

Eg. Consider 'Article' content type which is not a 'Standard group post'. By default Article access is restricted based on user role permission.
but using this module you can set Article access to the selected groups.

1. Set group based permissions to Article content type. (Eg. 'Create Article' permission to Group1)

2. Set role based permission in Drupal's permission page. (Eg. 'Create Article' permission to Authenticated user)

Now, users in permitted group and having permitted role can have appropriate access to content. (Eg. Only authenticated users from Group1 will have 'Create Article' access.)
