Hi,

Checking a bit more today, as the two changes on DC4 have *still* not 
propagated  to DC2/DC3, I discovered the
  samba-tool drs uptodateness
command.

I gives the following output, not sure what "unknown invocation ID" 
means. I hope someone here is able to explain..?

It's output:

Any idea what this means?

On DC3, it lists the same Unknown invocation ID, but ends differently:
> DOMAIN          maximum: 0  median: 0.0  failure: 0
> CONFIGURATION   maximum: 0  median: 0.0  failure: 0
> SCHEMA          maximum: 0  median: 0.0  failure: 0

Output on DC4 (the one where we made the change yesterday) looks like 
DC3 above.

Not sure what this means.

And worried that this samba-tool drs showrepl still shows nothing wrong 
at all, though there clearly IS an issue.

Warning to everyone: use the samba-tool ldapcmp command to verify LDAP 
contents between your DCs! Don't just trust your showrepl output..!
