Hello, I'm trying to give different types of permissions for each of my user groups. I have several projects and I want that groups can see only projects assigned to them. For example, the group customer relations should not be able to see the projects assigned to developers. I tried lots of things. When I assign just the project related to the group of CR and I remove the group of "users" the users of CR can not login. When I assign the project to the group of CR and "users", the users can see every project. What can I do?
