Hello Rowland,

I did comment the interfaces lines but nothing changed for the sysvolcheck on
dc2.
I also get an error message for ntacl sysvolcheck. The loglevel 5 output is the
following (for sysvolcheck in this case, I deleted some lines about loglevels
being 5):

For provisioning and joining I followed strictly the HowTos on the samba Wiki. I
used the following commands:

samba-tool domain provision --use-rfc2307 --interactive
--option="interfaces=lo eth0" --option="bind interfaces
only=yes" (provisioning on DC1)

samba-tool domain join example.lan DC -Uadministrator --realm=example.lan
--dns-backend=SAMBA_INTERNAL --option="interfaces=lo eth0"
--option="bind interfaces only=yes" (joining DC2)

I just came to the problem because I wanted to sync the sysvol between the two
DCs. But then I got this error-message on DC2.
My first thought was that something was wrong with the imported file, so I
started the procedure again, to see if I get the same error-message without
importing the data from DC1.

Strange, it seems to be saying that you do not have sysvol directory.

What does 'ls -la /var/lib/samba/sysvol/' show ?

and 'getfacl /var/lib/samba/sysvol'
