Disable Demo Users
Steps to reproduce
I noticed that the default Matterhorn configuration contains
Optional demo accounts with series memberships, but not
administrative rights. If set to 'true', 1000 users will be loaded
into the sample user directory. Usernames are user0, ..., user999.
Passwords are pass0, ..., pass999.
I would judge this as a security risk since it can be easily overlooked
by new adopters. Is there any reason why we should keep this enabled by
