You would like to prevent certain Notes client users from accessing their mail databases through a Web browser. Restricting HTTP access to the server is not an option, as this would prevent access from other users.
Three suggestions are below for accomplishing this goal:
1. Change the Internet password in the user's Person document. If the change does not take affect immediately, execute load updall -R names.nsf from the Domino server console.
2. Set the Maximum Internet Name and Password setting in the Database ACL > Advanced section to No Access.
Note: This will not prevent access to public documents, such as the Calendar. However, SPR# ASCR647JGQ was created for this behavior, however it is considered to be working as designed.
3. Enable the Don't Allow URL Open setting in Database Properties > Basics tab. When this property is set, the following error is displayed:
"Error 500 HTTP Web Server Lotus Notes Exception - You are not authorized to access that database".
Only users with a minimum of Designer Access to their mail database will have the ability to modify this setting.
Note: There is no way to programmatically enable this setting for multiple databases. It must be set manually for each database in question.
This issue has been reported to Quality Engineering as SPR# RSAR5F6FVW requesting that this setting be configurable using LotusScript.
