As you all probably know it's possible to associate a macOS user with an Apple ID.
You can open "User and groups" settings pane, select a user and ctrl-click to get an "advanced" menu that opens up a sub-pane where there is a field for specifying one (or more) Apple IDs.
Under this field there is also a box where you can add "aliases".
Using this setting has made it possible to connect to the user account on another Mac simply by clicking on the computer in the Finder sidebar (at least if file sharing is enabled). It takes a short while and then it connects displaying "Connected as <the apple id>".
With Sierra this no longer works for me (from 10.12.0 up to the current release 10.12.4).
What happens depends on the "age" of the user account.
If the user account was created using El Capitan (or earlier), the "alias" box mentioned above contains an alias that points to a keychain key, com.apple.idms.appleid.prd.<lots of stuff>. If I'm logged in as such a user (and the corresponding user on the other machine has the same alias) and try to connect, it takes quite a while, then connects, but displays "connected as com.apple.idms....." instead of the Apple ID.
If the user account is created using Sierra, or if I remove the associated Apple ID and add it again (to an old user), this alias is not present and the connection attempt simply times out after quite a long time...
If I click "connect as..." and select "Apple ID" the dialog box just "shakes its head" and refuses to connect.
It does not help to re-add the alias manually.
I know there are other ways to connect but this "connect by Apple ID" was a quite efficient way of doing occasional connects so I hope they will fix this...
