It means exactly what you do in your post-login script. It sets
master_user to same as user.

master_user is used for the ACL checks. Currently it doesn't do anything
else. So if you set master_user to "foo", it uses foo's ACLs when
determining access to mailboxes. There's nothing special about master
users after login, they're just usernames as any other usernames are.
