Odd. I certainly have the mount options in /etc/fstab, and using the
little test on the HOWTO
it's supposed to be working. However, listing the filesystem options
with tune2fs shows "none" for "Default mount options". "ext_attr"
does show as a feature in "Filesystem features" however.
To your other questions:
- I assume that provisioning the installation implicitly joined it to
the domain. This is the only domain controller on a very small
network. If provisioning didn't join it automatically, then no, it's
not joined to its own domain.
- Winbind isn't installed. I followed the HOWTO, but didn't see a
step about installing winbind.
Like I say, everything else appears to be working fine. I'm just
trying to wrap my head around the relationship between Samba's
internal users and the underlying filesystem permissions.
Thanks for you help!
