Today I got an error during a put into production operation. (I love getting new error messages I have never seen before when we go live with new projects )

A servlet that uses the web-users credentials to accesses information in several databases. Fortunately the problem was quickly resolved but it could have been a major show stopper.

The problem is that the user has web access to the server but do not have access to "Access the server". Apparently the servlet accesses the databases as a "Notes" user.

The solution is to add the users under Server document -> Security -> "Access server" .
