Cloning worked fine. I could not push/sync or auto sync over authenticated http. So I could pull down code, and serve that code. But the only way to sync would have been push over ssh, or pull from the server - which doesn't really scale with 26+ clients.

[ed: I'm away from the computers I tested on, but I remember I found quite a few stories like this, which all seemed to be a few years old, and had no resolution:

http://fossil-users.fossil-scm.narkive.com/iM7AQS3b/authenti...

Which is why I asked if anyone has been able to, with a current Fossil build, to:

On server "a" (in my case running Ubuntu 16.10, but testing both machines running Windows 10 would also be interesting): run fossil init ; fossil ui #change auth, register normal users user1, user2; fossil serve

Clone from a as user1, user2 on machine b with defined passwords (I got this far).

On b, run fossil ui, edit wiki as user1 and/or user2 - have sync work. Or edit and commit code and have sync work. ]
