I'm working on a database in which different users can fill in their hours. They should only have access to their own records. I know I can make different passwords and groups to organize this (I did it and it worked) but when the users change, I have to change the access privileges into each database (a lot of relations). Is there an easy way to arrange access privileges without a lot of editing. I tried 'gateway' but I can't get really into the program. (I can open it and see that it works, but I can't see how)
