Need public access to 2 content types and 2 folders

Is there a built in mechanism, or one someone has already made that will enable unauthenticated users to have the ability to create/modify data items in cms?

Alternatively, is there a way to set up some kind of Rx Community to LDAP OU relationship so that I don’t have to manually grant rights to all 150 of the people who should have access to my new content type but nothing else.

It’s possible to use the User Generated Content support (part of the Community Marketing Solution) to “submit” (but not edit) content as an unauthenticated user.

You should also be able to create an LDAP Group and assign that group to a Role (and Community).
