Hai Andreas,

Now, im not a team member, but..  Small question.

nmb.service has   Wants=network-online.target
samba.service has Wants=network-online.target

winbind.service not, why?
Could you give small explanation why winbind.service is not after network-online for my understanding.
What happens if a server starts, network.target is reached and no network is getting up.
A computer pass changes and winbind is unable to update the keytab..
Things like that is what i was thinking off.


Greetz,

Louis

man smb.conf -> winbind offline logon

"Wants" is a soft dependency a la LSB "Should-Start" and "Requires" is a hard
dependency a la LSB "Required-Start", right? Given that, "Wants=network-online"
makes perfectly sense for winbind.service for me, no?

Exacly.
And how about detecting the network interface names and "bind interfaces"

Winbind should just be started if the network is up, that's why it has:

After=network.target

That provides the basics we need to start winbind and have it functional for
login. If we delay the start of winbind the user might try to login but it
fails because there is not network ever coming up. He might not be connected
at all ...

the naming for that are a bit irritating but that sounds right now. But isn't
After=network.target then also what we want for the samba.service? The DC might
also not always be on a plugged network and it should start always IMHO. Also
local services might depend on it for example.

We added network-online.service because the DC doesn't start if it isn't
running:
