How do I set */MasterFile automatically in the ACL of each user's ID?

Setting */MasterFile in the Administration ECL on your Domino Server will automatically set */MasterFile in the ACL for a Notes user when they connect to the server or refresh their ACL settings.

From the Domino Administrator, open the Server Configuration tab and choose Actions > Edit Administration ECL.

From the dialog box that opens, click Add and then type */MasterFile.

Turn on every option under Allow and click OK.

*/MasterFile will now automatically be pushed to the ACL of a newly registered Notes user, when a user connects to the server, or when a user refreshes their ACL settings.

You can also add your own domain, i.e. */MyDomain in the same manner. When one of your users creates a case database, other users will then no longer have to answer the one or two security prompts that pop up the first time they access it.
