Very strange error - smb fails to start on Archlinux after upgrade from
4.8.5 -> 4.9.2 on a simple standalone server. This server has run for years
just fine through all upgrades, but on this one, smb cannot start:
# sc -l --no-pager status smb

Downgrading to 4.8.5 and all is fine. The config (testparm output) is:

The only place 'guest' is used is in the [printers] share with "guest ok =
Yes". I'm at a loss what the following is trying to tell me:
create_local_token failed: NT_STATUS_ACCESS_DENIED
ERROR: failed to setup guest info.
It doesn't tell me a whole lot other than something went South regarding
"guest info"? Why this is different in 4.9.2 from 4.8.5, I haven't a clue, but
4.8.5 works just fine. I have several other samba boxes with very similar
configs (other than they are not the browse master or win server or time server)
I've googled and found nothing related to 4.8 - 4.9 updates regarding this
error, or I just wasn't smart enough to find it. The bewildering part is I
have 2 other Arch servers with practically identical configs and they handled
the update just fine - so I'm not sure where to go from here. The only
difference between the boxes is that this one has probably been in service the
longest, going back to at least samba 4.1 -- if that makes any difference.
What to check?
