One of the things I've started to work on are some scripts to quickly be able to pull what a user's actual rights are within SQL Server. This is a question often asked by auditors and it would be great to give them a comprehensive answer. Just keying off the username isn't typically sufficient. After all, a user could have membership through groups, and access can be obscured because of roles, because of database ownership, etc. When you consider the web that can be formed with multiple roles, etc., it can be quite confusing to determine exactly what a particular user can do.
I'll post more as I make progress in this regard.
