Creation of new entity on ADEP content server fails

Question

Hi. 
I get the following error when trying to persist a new instance of an entity into the content (experience?) server:
Create Item Failed, RepositoryException: {Code}-LCC-REP-FCT-002, {Message}-Access denied
The new instance is defined in a Flex GUI and connected to the content Server through Data Services.  The error occurs when I try to develop the simple app shown in
Session #9: Using Model Driven Development with Persistence in the ADEP Content Repository (http://www.youtube.com/watthech?v=rNnLC8fADlc).
I have loaded the sdk, samples and cmis packages.  RDS and Unsecured RDS are enabled on the server.  The Deployment Handler is set to content on the Flex GUI.
I think it fails becuase the app does give appropriate security creditials to the server, but don't know how to do so (as commented by Hodmi on the YouTube page).
Would appreciate any help to make progress as I am keen to see what ADEP can do.
Regards
Jamal

Jamal-
Check out this link: http://learn.adobe.com/wiki/display/ADEPSamples/Model-driven+Development
In the Run the Application section, the step I've copied below will solve your issue.  I actually did not change the permissions on the "content" node (step 4), but selected my application node under content, and that also worked.
Have fun with ADEP!

PS-Thanks to Gary for pointing me in the right direction for this answer.
To create node or delete node when running the application, you can  use anonymous user but you need to configure the ACL for the user  according to the following steps:
Open http://<server_name>:<server_port>.
Enter admin/admin as user name/password, click Sign In.
Click Content Explorer in the right side panel.
Click the node “content” in the left tree.
In the top bar, click Security > Access Control Editor.
Click the check box next to ACL, then click Set selected policies.
Click New ACE, and then click Browse, select user, and click Search Now, select anonymous, and click select.
In Privileges list, select jcr:all.
Click the Green arrow, and then click OK
Note: If you want to add  authentication for the application, the login page should be needed, and  you can refer to the detailed sample code to learn how to add  authentication to such applications.
