Question: I would like to use a view field (node reference to an og group, configured to display a teaser) as rendered node inside a view and display the view to anonymous users. 
Do you know how to achieve this result ?

PS. Currently I can display it for admin user but for non-admin users the view field doesn't appear.

Answer: 
If you have the field\_permissions module installed make sure you check the settings for your view field and that the "view any value for field x" is checked for Anonymous users.
The display suite extras module creates a lot of field specific permissions. If some fields are missing, maybe its because the ds permission was not properly set.

**View Title on Node** is a new permission, for example. In my installation it was not set for anonymous users.
