[Samba] Authentication problem with Windows client

[Sven Schwedas]

I successfully joined a device to our Samba domain some weeks ago. Auth,
both online and offline, worked fine.

Now suddenly it stopped working. The device is online, the DC is
reachable, and I can log into samba member servers on the network just
fine, but not into AD accounts on that device.

I could remove the device from the domain using my domain credentials,
but now I can't re-join, it again doesn't recognize any credentials.
Logon on other devices and LDAP login via web services still works fine
everywhere.

How the hell do I debug issues like this?
