How to hide TeamCity configuration for selected users?

Question

I have one TeamCity project Dac.Test that contains 3 configurations: DEV, QA, PROD.

Answer 1

This is best accomplished by using TeamCity's built-in role management. Roles allow you to set fine-grained permissions for users and groups. One potential issue, however, is that roles are scoped to projects (not build configurations). You'll need to create a separate Dac.Test QA project+configuration and provide your Testers the necessary privileges there. You'll also need to make sure that they are stripped of all privileges for the Dac.Test project.
