node-demo.nsf, which comes with App Dev Pack, is the same design as Extension Library Demo database. IAM server functionality expects use of authentication, but the Extension Library Demo database doesn't secure any documents with Readers fields.
Also, the DQL Explorer application doesn't pick up State field from Contacts, because the field is missing from the Contact form. This version adds that field, as well as ConfigReaders and Readers fields (which are added for Reader security).
That is what this extended database provides. The Admin_Home XPage now has a Name Picker to select one or more users. If you don't select anyone, it works effectively as currently, because it sets the Readers field as “*“. If you select users, one or more are randomly assigned to each Contact. In addition, ConfigReaders field is set to “[Configuration]“, so the admin user can see all documents.
Don't forget to update the ACL, including assigning the “[Configuration]” role to the administrator. Also don't forget to sign the database, to avoid 403 errors.
